Question $2$:

Write an Octave an Octave function that accepts two matrices as input, adds them together element$-$wise using a nested for loop, and returns the sum. The function must conform to the following requirements:

i$.$ The function cannot just add the two matrices $-$ this is possible in octave, but you must do elementby$-$element addition.

ii$.$ You can check your result using the simple Octave addition.

iii. Note function must first check if the input matrices have the same dimensions. If they do$,$ it adds the matrices element$-$wise and returns the sum. If the dimensions are different, it throws an error.
