I have in my workspace two variables with different length how can I make them have same length in order to plot them in a graph ?

I have two different variables in my workspace and I want to plot them but they have different indice length one its 16x30000 and the other variable its 9x1200 What could I do ? any solutions?

Hello Manny Ram,

Let us consider Varibale A is having size of 16x30000 and B is having size of 9x1200

You can do this..

 newRowLength = max(size(A,1),size(B,1));
 newColLength = max(size(A,2),size(B,2));

 if ((size(A,1)~=newRowLength) || (size(A,2)~=newColLength))

     A(newRowLength,newColLength) = [0];
 end

 if ((size(B,1)~=newRowLength) || (size(B,2)~=newColLength))

     B(newRowLength,newColLength) = [0];
 end

Now A and B become of same length..

HI there, Thank you for answering. could tell me what size would it have ??

As per my given example..

The size of A and B will be now 16 x 30000

But this is the generic code, you can apply on any size of matrix, and it will give you the size of matrix as (greater number of row x greater no of column)

For example: If you have matrix C of 5 x 100 and D matrix of 10 x 50, then this code will give you new matrix C of size 10 x 100 and D also of size 10 X 100.

So that you can perform further operation.
