MATLAB: How to convert one large vector into an array of matrix

Question

I have a result column vector `yfit` containing result for multiple images one after another, for example, for images of size 512×512 the `yfit` would contain 1 to 262144 for first image, which further can be reshape() to get 512×512 result matrix. Further, 262145 to 524289 for second image's result matrix, and so on.

How to convert `yfit` in an array of matrix? Where each matrix would be a result of an image. Such as,

    x[1] => matrix of first image (512x512)
    x[2] => matrix of second image (512x512)

I am not sure, but it would be like

    x[1] = reshape(yfit(1:262144), 512,512);
    x[1] = reshape(yfit(262144:524289), 512,512);

What I want is `X` having result of all images. Thanks!!

Nitinkumar,

 yfit = 1:5*5*10;               % just as an exmple: 10 5x5 images
 x    = reshape(yfit,[5,5,10]);

You basically convert into a 3D array. The first image is accessed through

 x(:,:,1)
