How can I make a function where I ask two input matrices from user and do matrix multiplication using If-else conditions and error functions?

I'm new at matlab and I still don't know how this problem actually works. And I still don't know how to ask input from user at the first place. Can you help me please?

Look at input() function

a=input('enter matrix a: for example [1,5,9;2,4,6] ');

fprintf('For matrix input use the standard format\n e.g. [1 2 3;4 5 6]\n')
a = input('Enter first matrix: ');
b = input('Enter second matrix: ');

[m,n]=size(a);
[p,q]=size(b);

if n~=p
    disp('Error')
    return
end

Result = a*b

Use this template. I think this might help

Thank you so much for this. I actually inserted a similar code from you however, when I input a matrix with a size of Ex: 1x3 or 3x2, it displays an error of "Dimensions of arrays being concatenated are not consistent." What should I do?

show us the code

If the dimension is okay, then it should work. There might have some issue, regarding the input method.

For example:

1x3 matrix should be written as [1 2 3]

and 3x2 matrix should be written as [4 5;6 7;8 9]
