Subject: Do not use local ComplexMat variables
X-Git-Url: https://rtime.felk.cvut.cz/gitweb/hercules2020/kcf.git/commitdiff_plain/1c0345f519a389feac59d0dd9ad5dbfc6eeaa07d

Do not use local ComplexMat variables

After we convert ComplexMat to DynMem storage, we won't want to
allocate memory in every step.
