mot563_angle

Compute the phase angle of a real- or complex-valued signal.

MATLAB Syntax

Y=mot563_angle(x)

Description

mot563_angle returns the phase angles, in radians, of every elements within a matrix. Input elements can be complex.

Characteristics

In the workspace, if the input is:

x=[-0.6813 - 0.6822i   0.5028 - 0.1509i   0.3046 - 0.8600i;
   -0.3795 + 0.3028i   0.7095 - 0.6979i   0.1897 + 0.8537i;
    0.8318 - 0.5417i  -0.4289 - 0.3784i   0.1934 - 0.5936i]

mot563_angle(x,'56301')

then the returned value is:

ans=-2.3555   -0.2916   -1.2304
     2.4681   -0.7772    1.3521
    -0.5772   -2.4187   -1.2558

Arguments
X
   Vector (or matrix) with elements normalized in the range [-1,1] (for complex elements, both real and imaginary parts should comply with this limit).
