like this: clear all close all l 1 m1 zeros (3750,4) for k 1:9. You could also use disp (n) indZeroEl find (A0. There are also a lot of built-in functions to initialise matrices, etc. Instead, usually a problem can expressed in terms of matrix/vector operations. You should avoid explicit loops in MATLAB whenever possible. for n5:-1:1 decrements from 5 to 1 A-1 A is the vector you started with n by not suppressing the output with a semicolon will show the value of n in the command window. begingroup For loops are very slow in MATLAB. I'm assuming m1 () is an array, if it's a stuct or something else, change it accordingly. To output the iteration number each time, simply just put whichever variable you are iterating over inside the loop. Add m1 zeros (3750,4) in front of the for loop. 6.1.1 Using parfor-Loops The syntax and semantics of a parfor-loop in MATLAB software are the same as of the standard for-loop: MATLAB executes. The good news is that MATLAB supports Java objects, so you can do something like this: A = java.util. 3 Answers Sorted by: 1 You don't seem to preallocate memory for m1 (k,j). If you need to modify the data structure, you should use an appropriate Iterator instance which allows the addition and removal of elements in the collection you are iterating. If you want to be able to respond to changes in the data structure during iterations, a WHILE loop may be more appropriate - you'll be able to test the loop condition at every iteration, and set the value of the loop variable(s) as you wish: n = 10 ītw, the for-each loop in Java (and possibly other languages) produces unspecified behavior when the data structure is modified during iteration. This means that the following code always prints 1, 2, 3, 4, 5 regardless of the value of B. It tests the condition before executing the loop body. MATLAB's FOR loop is static in nature you cannot modify the loop variable between iterations, unlike the for(initialization condition increment) loop structure in other languages. Repeats a statement or group of statements while a given condition is TRUE. Using A For Loop To Create A Matrix In MatlabUsing a nested for loop to create a matrix that Learn more about for loop.
