Fixed SEE ALSO typo in help randperm.
Added the following new trigonometric functions:
haversin(x [,eps]) half versed trigonometric sine
hacoversin(x [,eps]) half coversed trigonometric sine
havercos(x [,eps]) half versed trigonometric cosine
hacovercos(x [,eps]) half coversed trigonometric cosine
ahaversin(x [,eps]) inverse half versed trigonometric sine
ahacoversin(x [,eps]) inverse half coversed trigonometric sine
ahavercos(x [,eps]) inverse half versed trigonometric cosine
ahacovercos(x [,eps]) inverse half coversed trigonometric cosine
Fixed calc regression test 42dd to set the display value back to 20.
Added test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.
Fix and improve recently comments and variable names added new
trigonometric functions in comfunc.c, func.c, qtrans.c.

DESCRIPTION
|
|
For a list or matrix x, randperm(x) returns a copy of x in which
|
|
the elements have been randomly permuted. The value of x is not
|
|
changed.
|
|
|
|
This function uses the rand() subtractive 100 shuffle pseudo-random
|
|
number generator.

EXAMPLE
|
|
; A = list(1,2,2,3,4)
|
|
; randperm(A)
|
|
|
|
list (5 elements, 5 nonzero):
|
|
[[0]] = 4
|
|
[[1]] = 1
|
|
[[2]] = 2
|
|
[[3]] = 3
|
|
[[4]] = 2
|
|
|
|
; randperm(A)
|
|
|
|
list (5 elements, 5 nonzero):
|
|
[[0]] = 2
|
|
[[1]] = 1
|
|
