How to code my own Reshape function without using the built in reshape()??

20 views (last 30 days)
Im essentially trying to make a function ---> function [matrix] = myReshape(vector, m, n) that takes in a 1d vector and dimensions m and n, and makes it a 2d matrix as shown above with the m and n provided.
How can I go about this?

Since MATLAB stores values in column order, note that your proposed "reshape" reorders the values in memory. I.e., it does not do the same thing as the MATLAB reshape( ) function. You have the equivalent of a transpose mixed in with this operation.

I see. Though transpose wouldn't necessarily work for me because if I want to end up with an uneven matrix of dimensions 3x4, I couldn't reshape and then transpose the reshaped matrix, because it would result in a 4x3 matrix ://

Hint: Notice the effect of doing things like this:
A=nan(3,4);
A(:)=1:12
A = 3×4
1 4 7 10 2 5 8 11 3 6 9 12

I recommend that you work backwards from the solution. What if you took the result that you are trying to get, and transposed that? What would that look like?
