Hi,

I have a cell array as below

cell_arr=

sub string as b = {'hard'}

If sub string matches with column1 i.e., cell_arr{:,1}, only that particular column2 has the value else it must be empty. i tried a lot with this.

out =

I am attaching the sample code here

a = {'hard';'smart';'hard drive';'smart work';'hark disk';'hard drive'};
b = {0.1;0.2;0.4;0.7;0.8;0.9};
cell_arr=[a,b];
out= cell_arr(strcmp(cell_arr,'hard'),:);

Please help me if any idea on this.

With modern Matlab versions >= R2016b:

a = {'hard';'smart';'hard drive';'smart work';'hark disk';'hard drive'};
b = {0.1;0.2;0.4;0.7;0.8;0.9};
c = [a,b];
% If the substring should be existing anywhere:
c(~contains(c(:,1), 'hard'), 2) = {[]};
% or if the substring should appear at the start:
c(~startsWith(c(:,1), 'hard'), 2) = {[]};
