Function for user to define any nxn matrix.

Hey gang,

For uni I need to create a function script that will allow a user to take any 2 nxn matrices and multiply them together.

I realise matlab can do this anyway but the exercise is to understand some of how matlab works.

My issue is that I don't actually know how to set it up so that my matrix will absorb any values put into it. From there I reckon I can do the assignment.

Any help would be just fab. Sorry if my request seems abit confusing, I can't think of how to word what I want very well.

Thanks!

Please read here, undestanding by ownself is better way of learning.

function mul_result=mul1(mat1,mat2)
mul_result=mat1*mat2;
end

Here mat1,mat2 can have any order of matrices,but please note that they must matrix multiplicable.

Save it (mul1.m) in your current working directory and call the function using mul1 from command or other scripts

See the Example, Command Window

>> A=randi(3,4)
A =
     3     2     3     3
     3     1     3     2
     1     1     1     3
     3     2     3     1
>> B=randi(3,4)
B =
     2     2     3     2
     3     1     3     1
     3     3     3     3
     3     3     2     1
>> C=mul1(A,B)
C =
    30    26    30    20
    24    22    25    18
    17    15    15     9
    24    20    26    18
