u
toRect
Function: Returns an equivalent rectangular form [
x y
] or [
x y z
].
Syntax: toRect (Mat [,natural number] [ ) ]
• This command can be used with a 1
×
N or N
×
1 matrix only (N = 2, 3).
• This command returns “
x
” when “natural number” is 1, “
y
” when “natural number” is 2,
and “
z
” when “natural number” is 3.
• This command returns a rectangular form when you omit “natural number”.
Example: To transform the polar form [ 2 ,
∠
(
π
/4)] into an equivalent rectangular form
(in the Radian mode)
