store the result of one row for 100 iterations to a matrix

HI i have this function which is sub main function. if i have 100 iterations in my main function that call my sub main function. i want code to store the FeatIndex matrix which is random values to store in a matrix for all the iteration so i can know what are theses random values in FeatIndex for 100 iterations.

function z=MinOne1111(x)
FeatIndex = randi([1 401],120,1)  
 x =  x([FeatIndex],:);
 z=  x ;
end

function [z, FeatIndex] = MinOne1111(x)
 FeatIndex = randi([1 401],120,1)  
 x =  x([FeatIndex],:);
 z=  x ;
end
