Variables defined inside functions are local to those functions unlessĭeclared as global both inside the function and at the command.There are various methods of referencing array elements (see below).* y % -> 2 8 18 (Dot before operator forces element-wise operations) > x * y % Default is matrix multiplication. Most Matlab functions operate on matrix and vector arguments in the expected manner.

> x = 0:0.1:100 % produces an array from 0 to 100 in increments > x = 0:100 % produces an array containing the integers (The irrational number is p i Pi has no predetermined meaning.)
