Histogram Matching result is not similar with inputs

Question

I'm trying to do histogram matching on two matrixes.But result is not similar with input matrixes.I think it must similar with histogram of "log_ort_esitlenmis".

esitlenmis=histeq(a);
ort_esitlenmis=fft2(esitlenmis);
log_ort_esitlenmis=log(1+abs(ort_esitlenmis));

%Image enhancement'ta butun imge icin sol sutun 
ort=fft2(a);
angle_ort_1=angle(ort);% 1.ortogonal(fft) icin faz bilgisi tutma.
log_ort=log(1+abs(ort));

matched=imhistmatch(uint8(log_ort),uint8(log_ort_esitlenmis));

This is the algorithm that I'm trying to do

Histograms of log_ort,log_ort_esitlenmis and mathced
