Coding Basics

1. A=[1,2,3,4,5] -> Creates a variable with the name A in a matrix dimension of 1*5

2. B=[1;2;3;4;5] -> Creates a variable with the name B in a matrix with dimension of 5*1 or transpose of A`

3. C = A*B` -> Syntax error, as the transposed of B(1*5) has the same matrix dimension of A (1*5), hence can\'t be multiplied

4. C = B*A -> Multiplication of two varible

Result = 1 2 3 4 5
2 4 6 8 10
3 6 9 12 15
4 8 12 16 20
5 10 15 20 25

5. A(1:end) -> Types the values of the variable A from the postion 1 in the matrix to the end of the matrix

Result = 1 2 3 4 5

6. A(1:2) -> Types the values fo the variable A from the postion 1 to 2 in the matrix in the matrix

Result = 1 2

7. B(1:2,3) -> Error: B(_,3): but B has size 5x1 = As the the matrix is in the dimension it can\'t fetch the non existant columns

8. B(length(B)-2) -> Gives the value 3rd position in the matrix, as it takes the length of the matrix and subtracts it by 2. The postion value is displayed
