I'm attempting to use ISMEMBER in order to obtain specific rows of data in a cell array. The code I'm currently using is:

% Clear WS variables and the comand window
clear all;
clc;
% Create a pair of cell arrays of strings
C = ["20749";"20750";"20751"];
A = cellstr(C);
D = ["20749" "11" "ABC-21"; "1000" "35" "XYZ-54"; "20749" "113" "BXT MNT"; "20750" "400" "ABC-21"; "2000" "35" "ABC-01"; "20751" "42" "SRT-29"; "2001" "60" "ARN-21";"20750" "80" "ABC-21"; "20749" "25" "ABC-21"; "3000" "14" "ABC-21"];
B = cellstr(D);
% Array elements that are members of set array
[Lia,Locb] = ismember(A,B,'legacy');

I've run into a problem where Locb contains the lowest index in B for each value, instead of all the indices. Eventually I'd write the applicable rows of data in B into a separate variable. Is there a technique I could utilize that would allow for this? Or will I need to use a different function/technique?

Thanks.
