|| Welcome to the spoken tutorial on Vector Operations

|-

| 00.07

| | At the end of this spoken tutorial you will be able to,

|-

| 00.11

| | Define a vector.

|-

| 00.13

| | Calculate length of a vector.

|-

| 00.15

| | Perform mathematical operations on Vectors such as addition,subtraction and multiplication.

|-

| 00.23

| | Define a matrix.

|-

| 00.25

| | Calculate size of a matrix.

|-

| 00.28

| | Perform mathematical operations on Matrices such as addition, subtraction and multiplication.

|-

| 00.36

| |The Pre-requisites are Scilab should be installed on your system.

|-

| 00.41

| | You should have listened to the Spoken Tutorial on Getting started with Scilab.

|-

| 00.46

| | You should have Basic knowledge about Vectors and Matrices.

|-

| 00.50

| | I am using Windows 7 operating system and Scilab 5.2.2 for demonstration.

|-

| 00.58

| | Click on Scilab shortcut icon on your Desktop to launch Scilab.

|-

| 01.03

| | This will open the Scilab console window. Notice that the cursor is on the command prompt.

|-

| 01.11

| | I suggest that you practice this tutorial in Scilab simultaneously while pausing the video at regular intervals of time.

|-

| 01.20

| | Let us start by defining a vector.

|-

| 01.22

| | This can be done in two ways:

|-

| 01.24

| | by using spaces as p is equal to open square bracket one space 2 space 3 close the square bracket and press enter.

|-

| 01.37

| | or using commas as q is equal to open square bracket two comma three comma four close the square bracket and press enter.

|-

| 01.54

| | We can find the length of a vector p by the command length of p and press enter

|-

| 02.03

| | We can perform various mathematical operations on vectors such as

|-

| 02.08

| | Addition of two vectors:

|-

| 02.11

| | Substraction of two vectors and so on.

|-

| 02.15

| | Transpose of a vector can be found by using apostrophe (also known as single-quote).

p transpose is as shown

|-

| 02.28

| | We can calculate p-transpose times q:

|-

| 02.35

| | The command p times q-transpose gives a scalar:

|-

| 02.44

| | Please pause the tutorial now and attempt exercise number one given with the video

|-

| 02.51

| | Now we will see how to define a matrix.

|-

| 02.56

| | Elements of a row of a matrix, can be defined using spaces or commas similar to that shown for a vector

|-

| 03.04

| | For example,let us define a 2 by 3 matrix P by typing captital P is equal to open square bracket 1 space 2 space 3 semicolon 4 space five space 6 close the square bracket and press enter.

|-

| 03.27

| | Note that Semicolon is used for defining the next row of the matrix.

|-

| 03.32

| | Recall that Scilab is case sensitive.

|-

| 03.35

| | Here variable P used to define matrix is in upper case.

|-

| 03.40

| | Which is different from small p that was a vector.

|-

| 03.44

| | Would you want to check what small p is at this point?

|-

| 03.48

| | We will now see how to find the size of a Matrix using the “size” command.

|-

| 03.54

| | for this type open square bracket row comma column close the sqaure bracket is equal to size of capital p which is matrix and press enter.you get the following output.

|-

| 04.18

| | Note that the length command will give the total number of elements in the matrix as you see.

|-

| 04.28

| | The transpose command works for matrices as well as shown here :

|-

| 04.35

| | p transpose gives the transpose of matrix p.

|-

| 04.42

| | Let us now define a 2 by 3 matrix Q:

|-

| 04.45

| | capital q is equal to \open square bracket one space five space three semicolon to enter into the

|-

| 04.56

| | next row two space four space eight close the square bracket and press enter.

|-

| 05.04

| | Let us also recall P once more:

|-

| 05.09

| | We can carry out calculations involving P and Q, just as we do in mathematics.

|-

| 05.15

| | For example, let us calculate E is equal to 2 times e plus 3 times q and press enter:

|-

| 05.29

| | You may want to verify whether these calculations are correct.

|-

| 05.34

| | Please pause the tutorial now and attempt exercise number two given with the video

|-

|05.45

|In this tutorial, we have learnt to

|-

| 05.47

| | Define a vector using spaces or commas.

|-

|05.50

| | Calculate length of a vector using the length() function.

|-

| 05.54

| | Find the transpose of vector or matrix using apostrophe.

|-

| 05.59

| | Define a matrix by using space or comma to separate the

|-

| 06.04

| | columns and semicolon to separate the rows.

|-

| 06.07

| | Find size of a matrix using size() function.

|-

|06.11
