asin
sine inverse (radians)
Syntax
t = asin(x)
Arguments
- x, t
arrays of real or complex numbers, of same sizes.
Description
The entries of t
are sine inverse of the
corresponding entries of x
.
Examples
x = 0:0.2:1; x = [-x ; x] asin(x) A = [1,2 ; 3,4]; a = asin(A) sin(a)
--> x = 0:0.2:1; x = [-x ; x] x = 0. -0.2 -0.4 -0.6 -0.8 -1. 0. 0.2 0.4 0.6 0.8 1. --> asin(x) ans = 0. -0.2013579 -0.4115168 -0.6435011 -0.9272952 -1.5707963 0. 0.2013579 0.4115168 0.6435011 0.9272952 1.5707963 --> A = [1,2 ; 3,4]; --> a = asin(A) a = 1.5707963 + 0.i 1.5707963 - 1.3169579i 1.5707963 - 1.7627472i 1.5707963 - 2.0634371i --> sin(a) ans = 1. + 0.i 2. - 1.061D-16i 3. - 1.732D-16i 4. - 2.372D-16i
