MATLAB Online에서 열기 Ran in: This issue arises because the first bin edge is at x=0 andlog(0)=-infwhich cannot be represented graphically. Assuming there are no data less than or equal to 0 and no bin edges less than 0, you could set the first bin edge according to the ...
ifP(n,m)>0 ent = ent - P(n,m) * log10(P(n,m)); end end end here's the error message: does anyone know what should I do to execute that function? Thanks.
MATLAB Online에서 열기 hi guys. i created a signal CW in time domain with Gaussian noise. i need to to check what is the amplitude value in several specific frequencies? by doing FFT i do not get a good result, so i taught using th...
Hi Does anybody knows how to use fit in log(Y). I mean I have x and y data, I am plotting it and fitting points by straight line using matlab toolbox. When I take log in Y axis my straight fit line becomes curve line. I want straight line fit not curve fit. ...

I struggled for a while to decide what program(s) were appropriate – ADS, SPICE, Mathcad, Matlab, etc. – but chose Python since I need to improve my Python skills. This took several days to write as I was going through the Python/NumPy/SciPy learning curve along...
