If you want Matlab to resolve the name, you'd need to write something like. At the end i get a value of c that is of the order of 3x2, that is the final value that comes after3rd iteration. Open Live Script. The right-hand side of the assignment in a for loop can be any row vector. 0 ⋮ Vote. The user is then asked what would they like to do, and if they write add book, a new title author and number of pages should be given.

Commented: Mary Jon on 4 Dec 2013 Accepted Answer: Walter Roberson. I need some help with Matlab. Matlab reads this as a variable literally named volt_ii which is the same on every iteration of your loop. Vote. Its simplest form is (loop (print "hello")): this will print forever. Wenn Sie möchten die Anzahl der Zeiten, die die while Schleife eingegeben wurde, der einfachste Weg ist es, deklarieren Sie eine variable außerhalb der Schleife und der Inkrementierung innen: .
