Matrix multiplication

Microsoft excel provides a function for matrix multiplication. Matrix multiplication process in microsoft excel accordance with the rules of the matrix. As with addition and pegurangan matrix. In our matrix multiplication is also doing an array of product from range of data. we will try to multiply two matrix (3x3 order)

1. Create a matrix as below (only accecories bracket, can be ignored)




2. Block range to put the product (adjusted order to the matrix results)
notes:
Order the product matrix = (mxn) (mxn) = (nxm)



3. Type the formula:
=MMULT(A4:C6,E4:G6)

Counting the number of characters

In the microsoft excel, you can count the number of characters (text or numbers), for example could see data table below
In column A is the set of characters, which will be selected and counted characters A, B, A1, A1B2, A2B1



To calculate the character, then create the following fomula:
In cell B6, type the formula:
= LEN (A6) - LEN (Substitute (A6, "A ",""))
in C6 cell type the formula:
= LEN (A6) - LEN (Substitute (A6, "B ",""))
in D6 cell type the formula:
= (LEN (A6) - LEN (Substitute (A6, "A1 ","")))/ 2
in E6 cell type the formula:
= (LEN (A6) - LEN (Substitute (A6, "A1B2 ","")))/ 4
in F6 cell type the formula:
= (LEN (A6) - LEN (Substitute (A6, "A2B1 ","")))/ 4



Choosing the existing text in brackets

Maybe there are friends who sometimes find the excel data format such as the table below

look at column A, contain data a name and email,
in the following cases we can choose an email-only (character / text in bracket)




To select an existing text in brackets, on the cell B5 type the formula:

= MID (A5, FIND ("(", A5) +1, FIND (")", A5)-FIND ("(", A5) -1)




Power Function

Microsoft excel has provided power function. You can calculate the power of a number. For example you can see the following examples:

1. create a table like the following
We will calculate the power of the existing numbers in column A, then calculate the power (power 2 in column B) and power 4 in column C




2. Below we will try to use the power formula;
General formula:

= POWER (number, power)

a. the input formula B4 cells
= POWER (A4, 2)
b. In the cells enter the formula C 4
= POWER (A4, 4)

You also can use another formula, such as:
General formula

= number ^ power

a. In cell B11 type the formula
= A11 ^ 2
b.a In cell C11 type formula
= A11 ^ 4

You can see the result as below



Function square root (square)

Microsoft excel provides a function to calculate (calculate) the root of a number, you can calculate the square root, cube root, and so on.

Here is a simple example:

1. Create a table like the following
(table with a light blue background, not fill because the content will be filled a formula)





2. In cell B4 content of the formula:

= SQRT (A4)

other than the above formula you can use the formula:
a. B10 cells, you can calculate the square root of the number of cells with the formula A10:

= A10 ^ 0.5

b. or in cell C 10, you can calculate the cube root of the number of cells with the formula A10:

= A10 ^ (1 / 3)

the result will look like the image below



Trigonometric functions (sin, cos, tan)

One of the mathematical functions that can be used in the microsoft excel is trigonometric functions. some of these trigonometric functions is to calculate the sine (sin), cosine (cos) or tangent (tan) of a corner.

In order to more easily able to see the example below:

1. Create a table:



trigonometric

2. the color table gray background will be filled with the formula
a. To calculate the sine value, in cell B4 type the formula:
= SIN ((A4) * PI () / 180)

b. To calculate the sine value, in cell C4 type formula:
= COS ((A4) * PI () / 180)

c. To calculate the sine value, in the D4 cell type formula:
= TAN ((A4) * PI () / 180)

sin cos tan



Matrix addition

 Microsoft excel provides a function to martix addition. Add process in accordance with the rules of the matrix, the matrix can be added if they have the same order.
Here we will try to add the matrix (4X4 order)

1. Create a matrix as below (only accecories barcket, can be ignored)



matrix addition

2. Block range to put the sum (adjusted the same order of a matrix that will add )



3. Type the formula:
= A4: C7-E4: G7

matrix

Perform array by pressing the key combination Ctrl + Shift + Enter

4. The result will look like the image below

Getting to Know ArcGIS Desktop: The Basics of ArcView, ArcEditor, and ArcInfo for ArcGIS 9


This book provides a tour of the ArcGIS integrated development environments for ArcMap and ArcCatalog, and it does a good job of it. It's definitely intended for absolute newcomers to ArcGIS software-- it walks you through step-by-step exercises to explore many of the software's features.



The step-by-step exercises are carefully written and extremely detailed-- almost too detailed. Each exercise gives full instructions for every step, even steps you performed in earlier exercises. I wish the book would have only given detailed instructions the first time you performed a particular task. I think this would help the reader commit the information to memory and really learn the software instead of just following the steps again in each exercise.


With revised material and new exercises based on ArcGIS version 9, this updated work acquaints geographers and GIS professionals with the principles of GIS as it teaches the mechanics of using ArcGIS software. Conceptual material is followed by scripted software exercises. Necessary GIS skills are presented in a variety of areas-map symbology, data overlay, map projection, and data conversion-as the making of maps and the analysis of geographic data is conceptualized. Spatial modeling exercises using the ModelBuilder technology of ArcGIS version 9 are also provided. Other topics covered include organizing data, planning a GIS project, creating derived data, and presenting results.
