Suppose I have a vector x=[1 2 3 4 5] and y=[1 1 4 2 1 5 2 5 1 1]. I have to count frequency of occurance of each element of x in y.
For this particular example 1-->5, 2-->2, 3-->0, 4-->1, 5-->2 therefore output should be z=[5 2 0 1 2].
Thank you.

x=[1 2 3 4 5];
y=[1 1 4 2 1 5 2 5 1 1];
%hiscounts has an automatic binning algorithm
out1=histcounts(y)
If you wish to include x as well in the code -
histcounts combines the last two bins into one, so modify the bins accordingly
out2=histcounts(y,[x x(end)+1])
Using histc(), but note that histc is not recommended to use by MathWorks
out3=histc(y,x)
