For example, see the code below. MATLAB allows you to use either a row and column index, or a single linear index. That way you can simulate nested for loops that begin somewhere in the table and finish not at the end. The idea of a linear index for arrays in matlab is an important one. How can I iterate through two arrays at the same time without re-iterating through the parent loop? In that case the size of the array you're assigning into Q would need to be based on the number of, values in the index vector rather than the number of elements. Maybe there is a "vectorized" way to do it instead Also, if you wanted to recover the indices for some reason, you still could using these two simple commands: Indexing in 64-bit MATLAB does indeed correctly allow 64-bit subscripts. And using a loop and linear indexing, we displayed each element one by one on the command window. @rayryeng you are not right. You can use linear indexing to access each element. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide.
