Matlab: Create Matrix from Single Column Data

[rishabhdutta]

I have a single column data of say length 1000. I want to make a matrix m * n using that data. m*n may need not be 1000, it can be less. looking for the script.

If you're allowed to use built-in commands, you can use 'reshape':

If you're not, you're going to have to do some looping:

We can't do your work for you, however.

Thank you for the effort.

Had to use looping. reshape couldn't help me much as the no. of elements in the desired matrix have to be same as in the provided matrix form. for eg. I would like to get 4*3 matrix from the 15*1 matrix

Do you know how to extract parts of vectors / matrices using the colon (:) operator? If not, it's a very useful thing to know:

For instance:

A=ones(4,3);
B=eye(3);
C=A(1:3,:)-B;
