Hi,

I have a cell array of cells (see attachment) and need to covert each of the cells into numeric arrays for further processing.

How can I do that in one go?

Thanks!

在 MATLAB Online 中打开

pre_data_1.mat

S = load('pre_data_1.mat')
S = struct with fields:
    pre_data1: {2×1 cell}
S.pre_data1
ans = 2×1 cell array
    {13757×21 cell}
    {13150×21 cell}
S.pre_data1 = cellfun(@cell2mat,S.pre_data1,'UniformOutput',false);
S.pre_data1
ans = 2×1 cell array
    {13757×21 double}
    {13150×21 double}
