MATLAB: Cell2mat Error :using cat Dimensions of arrays being concatenated are not consistent.

Question

Hello,

I have a cell array which is as follows:

I am using

P2 = cell2mat(Numerical_FourierForce{1,1})

and I get this error:

Error using cat

Dimensions of arrays being concatenated are not consistent.

Is there any way to avoid this error?

Because in the picture, I have some cells with 0 and some with two values, these values are forces in x and y and zero is for both of them.

Is ther any way, I could convert them into ordinary array?

Answer 1

%P2 = {0,[1;2];0,0}; % test data
P2 = Numerical_FourierForce{1,1};
X = cellfun(@(a)isequal(a,0),P2);
P2(X) = {[0;0]};
P2 = cell2mat(P2)
