Remove elements in cell array based on index of elements

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

Answer 1

for ki = 1:length(difceller)
    condition1 = cellfun(@(x)(x<0),difceller,'UniformOutput',false);
    smcellere = cellfun(@(x,y) ~y(x==1),condition1,smceller,'Uniform',0);
    errorcellere = cellfun(@(x,y) ~y(x==1),condition1,errorceller,'Uniform',0);
end

This answer removes based on Index

Answer 2

[Jonathan Cheong]

for ki = 1:length(difcell)
    condition1 = cellfun(@(x)(x<0),difcell,'UniformOutput',false);
    gk = cellfun(@(x,y) y(x==1),condition1,smcell,'Uniform',0);
end
smcellclean = cellfun(@(x,y) x(~ismember(x,y)), smcell, gk,'Uniform',0);

Instead of using index I find values that are the same and removed them.
