dwarning 794a37339a ifft: in case input array is smaller then output array - fill in the rest with zero to prevent uninitialzed plot variables 2023-07-15 11:32:11 +02:00
dwarning 42b803e5c2 same array size for in- and output in inverse fft function from fftw3 2023-07-15 11:31:59 +02:00
Holger Vogt 0ee5e3f32a Add a control language function cvector, to create a complex vector.
Let vec1 = cvector(50)
will generate a complex vector, with the real part values
increasing from 0 to 49, the imaginary values are set to 0.
Useful in ac loops to store result data.

Holger Vogt 02789b2c42 The modulo function a % n should accept a==0.
The fix adds this to the control section function parser. The numparam
parser already has this feature. n==0 is rejected as usual.

Holger Vogt 26c50de68b function deriv: This is just a preliminary fix: prevent a crash
when base > 0.

But when is base supposed to be > 0 ? More invetigation is needed.

Holger Vogt 4dbd8b7f9a Preliminary fix for the 'interpolate' function.
Interpolation of 1D vectors is o.k. now,
multi-dimensional vectors are not (yet) supported.
