comunwrap()
Description:
Shift phase angles.
Syntax:
comunwrap(A,tol,dim)
Note:
The external library function (See External Library Guide) unwraps radian phase angles of sequence A of complex numbers according to dimension dim. Whenever the jump between consecutive angles is greater than or equal to tol radians, comunwrap shifts the angles by adding multiples of ±2π until the jump is less than tol.
Parameter:
|
A |
A sequence of complex numbers. |
|
tol |
The jump threshold value. |
|
dim |
Dimension; unwrap by column when its value is 1 and by row when its value is 2. . |
Return value:
Sequence
Example:
|
|
A |
|
|
1 |
=[[0,7.07],[0.19,0.98],[6.67,1.18],[0.59,1.37],[0.78,1.56]] |
|
|
2 |
=comunwrap(A1,3.14,1) |
Unwrap A1 by column, with a jump threshold value of 3.14. |
|
3 |
=comunwrap(A2,3.14,2) |
Expand A2 by row, with a jump threshold value of 3.14. |
|
4 |
=comunwrap(A1,1.2222,2) |
Expand A1 by row, with a jump threshold value of 1.2222. |
