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

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)

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.
