How to combine arrays of different size into a single cell array?

I am working on DWT in MATLAB, and I want to decompose a 1-D input vector into three levels. The output of the DWT is: 

w =

  1×4 cell array

    [32×1 double]    [16×1 double]    [8×1 double]    [8×1 double]

I have processed each coefficient separately:

a = w{1}; b = w{2}; c = w{3};  d = w{4};

I want to combine a, b, c, and d to get the same as w. I have tried mat2cell and w = (a; b;c;d) but I am not getting the same as w. Any idea how to do that?

Solution

  • If you're wanting to put a, b, c, and d back into a cell array (like w that you took them from), you just need to use curly braces:

    w = {a, b, c, d};
