FLTARR

Syntax | Return Value | Arguments | Keywords | Examples | Version History | See Also

The FLTARR function creates a floating-point vector or array of the specified dimensions.

Syntax

Result = FLTARR( D₁[, ..., D₈] [, /NOZERO] )

Return Value

Returns a single-precision, floating-point vector or array.

Arguments

D_i

Either an array or a series of scalar expressions specifying the dimensions of the result. If a single argument is specified, it can be either a scalar expression or an array of up to eight elements. If multiple arguments are specified, they must all be scalar expressions. Up to eight dimensions can be specified.

Keywords

NOZERO

Normally, FLTARR sets every element of the result to zero. Set this keyword to inhibit zeroing of the array elements and cause FLTARR to execute faster.

Examples

Create F, a 3-element by 3-element floating-point array with each element set to 0.0 by entering:

F = FLTARR(3, 3)
