FLTARR Function

FLTARR Function

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

enabled.

Usage

result = FLTARR(dim1, ..., dimn)

Input Parameters

dimi—The dimensions of the result. May be any scalar expression. Up to eight dimensions may be specified.

Returned Value

result—A single-precision floating-point vector or array.

Keywords

Nozero—If Nozero is nonzero, this zeroing is not performed, thereby causing FLTARR to execute faster.

Discussion

Normally, FLTARR sets every element of result to zero.

Example

PRINT, FLTARR(4)

; PV-WAVE prints: 0.00000   0.00000   0.00000   0.00000

PRINT, FLTARR(4, /Nozero)

; PV-WAVE prints four floating point values, e.g:

; 5.60519e-45  1.98225e-39  2.35149e-38 5.60519e-45
