Hi everybody,

M = [0.3  0.4   4; ...
     0.5  0.6   3.1];
nRow = size(M, 1);
for iRow = 1:nRow
    yourOperation(M(iRopw, :)) ...
end

If you want to collect the results, use either a matrix again:

result(iRow, :) = ...

Or if the output has different sizes or classes, use a cell array:

Result = cell(1, nRow);
for iRow = 1:nRow
    Result{iRow} = yourOperation(M(iRopw, :)) ...
end
