Re: Vector into array...

[Steve Hankin <hankin@xxxxxxxxxxxxx>]

Hi Gary,

The RESHAPE function is the hot ticket for this. An example to illustrate -->
reshape a "vector" of length 50 into a 2D array that is 5x10:

     let my_one_D = i[i=1:50]
     define axis/x=1:5:1 xax
     define axis/y=1:10:1 yax
     let my_2D = RESHAPE(my_one_D, x[gx=xax]+y[gy=yax])
     list my_2D
