Hello, I would like to remove elements in a cell array based on index number from another cell array.

For example:

A = [1, 15, 25, 30] B = [1, 4]

A is the data cell array, B is the cell array with indices of elements I want to remove

Output:

A = [15, 25]

for ki = 1:length(difcell)
    condition1 = cellfun(@(x)(x<0),difcell,'UniformOutput',false);
    gk = cellfun(@(x) find(x==1),condition1,'UniformOutput', false);
%     I'm stuck at this stage
%     smcell = cellfun(@(x) x(gk), smcell, 'Uniform', 0);
end

Many thanks in advance.

Just to clarify!

'gk' is the index cell array

'smcell' is the data cell array
