dfreq
Frequency vector function.
Syntax
dfreq(vec_expr)
Argument
- vec_expr
- A valid vector expression.
Example
Curve Math Vectors | Result |
---|---|
x = dfreq(c1.x)
|
A vector which is the frequency component for a frequency domain curve is created using the sampling interval from c1.x. |
Comments
The dfreq function builds a frequency axis from time-domain data. The resulting vector is suitable as a frequency axis for any of the discrete frequency domain functions. The result has a number of elements equal to the number of elements in vec_expr. dfreq assumes that vec_expr is evenly sampled.
