I have a 1x44 cell with different dimension. I want to change those cell in to single matrix so that I can do manipulation? I try cell2mat but no luck. Is there any way to change cell to matrix of different dimension?

Yes, each cell in the cell array is with different dimension. when i try cell2mat it says "Dimensions of matrices being concatenated are not consistent"

This is the cell array I have. I want to change this cell to matrix but it has different dimensions.

"Is there any way to change cell to matrix of different dimension?"

Not to a numeric matrix, No. Numeric matrices require consistent dimensions.

You could potentially pad the various parts out with NaN or inf or 0 as required so that the parts were the same shape. That gets a bit complex if the arrays might be different numbers of dimensions.

在 MATLAB Online 中打开

ColFirstN = @(V, L) V(1:L);
ColPad = @(V, L) ColFirstN( [V; zeros(L, 1)], L);
maxlen = 18000;
padded_gm = cellfun(@(V) ColPad(V, maxlen), gm), 'Uniform', 0);
gm_matrix = cell2mat(padded_gm);
