Please, how do I implement this on MATLAB? I would like to find the difference between the value of let say x3 minus the maximum value of y that fulfils the condition x3>= y(--)? For example, if x= [106, 306, 407, 607, ...] and y = [101, 201, 301, 401, 501,...], at x(3), this difference will be 407 - 401 (401 is the max value less than x(3)).
for i= 1: 100
x = [x1,x2,x3,...]
y= [y1,y2,y3,...]
Time = %the difference between the value of let say x3 minus the maximum value of y that fulfils the condition x3>= y(--)?
end

for given vector x and y;
x= [106, 306, 407, 607] % given x vector
y = [101, 201, 301, 401, 501] %givrn y vector
d=[];
for ii=1:length(x)
for jj=1:length(y)
if x(ii)>=y(jj)
d=[d,y(jj)]; %vector of all elements which is less than x say X(3)
end
end
diff=x(ii)-max(d); %differnece
d=[];
end
