I have a matrix A and avector y. I want to create a loop which names and defines them the matrix A from A1,...,A10. fori = 1:10 A{i} = X(y==i) end Unfortunately this code does not work. It would be nice to end up with a double and not a cell ...

It's time to explore the virtual land of Loopindex! Its vast, uncharted lands are full of puzzles to solve! Play alone, or team up with a robo-friend, and use logic and timing to clear each area. The difficulty will test your ingenuity as you explore the unique “loop mechanic” at...
Current unit vector: 0 1 0 0 Current unit vector: 0 0 1 0 Tips To programmatically exit the loop, use abreakstatement. To skip the rest of the instructions in the loop and begin the next iteration, use acontinuestatement. Avoid assigning a value to theindexvariable within the loop state...
Let’s take a closer look at common ways aforloop can causeList Index Out of Rangeand how to either avoid it completely or gracefully handle this error when it crops up. What causes the “List Index Out of Range” error? As Python uses zero-based indexing, when you try to access an...
