Number in a cell to a row number in loop.

Hello! I have a matrix containing numbers [8 88 67 74] and so on, and I want matlab to take these numbers as 'row numbers' of an another matrix. How should I do this?

@Neje: what would the expected output be?

[Neje]

I want to perform row operations on these numbers. But do not want to put these numbers manually. (they are already present in an another matrix)

if true
  %code 
for i=8,88,67,74 
end

If you're just looking to use those values as row selection you can enter them as the index of your value:

for k = 1:length(rownums);
   results = data(rownums(k),:); % Include your operations here, but the indexing for your data should call
                                 % the entire row specified by the kth value of your first matrix of row
                                 % numbers.
end

Thanks! It works :)

But it throws as an error for 'data' function as follows.

Undefined function 'data' for input arguments of type 'double'.
