Question

Please help me with this. PLease make all the steps clear. .........

24 Assume a matrix variable mat, as in the following example: ma t = 2 1 2 The following for lo 4 402 op r, size (mat) for i = 1:r sumprint (mat (i, : ) ) end prints this result: The sum is now 15 The sum is now 25 The sum is now 37 Write the function sumprint.

Answer 1

Explanation of Code:

In the first line, we are declaring a matrix(3 X 5)

then [r,c] = size(mat); We are unpacking the values of rows and columns in variables "r" and "c".

then we are initializing our for loop from values 1 to r,

then we are calling sumprint function which is printing the sum of every row of the matrix

sumprint(mat(i,:) , represents that we are accessing "ith" row and all columns of matrix mat

and in the end it is printing the sum of elements of all the rows one by one

Sumprint function is basically accepting a row of matrix(can be considred as a vector) and giving the sum of all its elements.
