Hello,

I have a cell array, called cell1, containing a list of string variables. I would like to remove all variables with the same name in a second cell array, called cell2, and generate a thrid cell array, called cell3, with data from cell2 that were not present in cell1.

For example, let say that cell1 and cell2 are:

cell1 = {'aaa';'bbb';'ccc';'ddd'};
cell2 = {'bbb';'eee';'fff';'aaa';'ccc'};

How to get:

cell3 = {'eee';'fff'}

Thank you in advance,

Guillaume

在 MATLAB Online 中打开

cell1 = {'aaa';'bbb';'ccc';'ddd'};
cell2 = {'bbb';'eee';'fff';'aaa';'ccc'};
cell3 = setdiff(cell2,cell1)
cell3 = 2×1 cell array
    {'eee'}
    {'fff'}
