Calculate mean of column in structure if another row = 1

I have a structure that has columns Correct (either 0 or 1) and Latency. I am attempting to calculate a mean of the Latency values ONLY if correct = 1. So the Latency mean value from the data set below I am hoping to get is 402

Correct  Latency
  1     325
  0     359
  1     410
  1     425
  0     371
  1     448

I have attempted something like this:

if struct.Correct == 1
latmean = mean(struct.Latency)
end

But I get the error "Error using == Too many input arguments"

Any thoughts on a way to achieve this? Thanks

As a follow-up question what if I add another array to the cell below

       1     0     1     1     0     1
     325   359   410   425   371   448
       4     4     4     5     5     5

Now is it possible to give an output separately for out=mean(B(2,logical(B(1,:)))) dependent on whether array 3 == 4 or 5?

Thanks

v=[  1     325
0     359
1     410
1     425
0     371
1     448]
A=struct('correct',num2cell(v(:,1)),'latency',num2cell(v(:,2)))
B=cell2mat(struct2cell(A))
out=mean(B(2,logical(B(1,:))))
