double

onvert to double-precision

Syntax

• double(X)
  

Description

double(x) returns the double-precision value for X. If X is already a double-precision array, double has no effect.

Remarks

double is called for the expressions in for, if, and while loops if the expression isn't already double-precision. double should be overloaded for any object when it makes sense to convert it to a double-precision value.
