Finding Min Value in array with changing condition

3 views (last 30 days)
Hello guys,
I got a matrixs which are like ;
a=randi([0,1],1,5)
cost=[6739,10355,7650,5219,5776]
in this changable conditions I want to find the min value.
For example;
a= [1 0 0 0 1]
cost=[6739,10355,7650,5219,5776]
min cost = 5776 according to matrix a

tf = a == 1 % create a logical array
temp = cost(tf) % logical indexing to retrieve certain values
mincost = min(temp) % use a dedicated function to find th minimum value
I leave it to you to make this a single statement!
