MATLAB: Comparing all the elements of an array with all the elements of another array

array

Hello ,
I want to compare Compare all the elements of an array with all the elements of another array and save the result to a now array.
i have an array A=[100 110 120 130…..600]
which i want to compare with B = [100 103 105 120 123 128 130 200 205 207 300 200 100 ]
if the value of B mateches with any element of array the value of A sholud be stored in new array C and the value should not repeal(like if there is already 100 in the array C then i should not write it again. )
the output should look like this
C = [100 120 130 200 300]

Best Answer

This returns the elements in order as in B, from left to right
A = 100:10:600
B = [100 103 105 120 123 128 130 200 205 207 300 200 100 ]
C = unique(B(ismember(B,A)),'stable')
