Exponential on matlab - Basically, while translating code from Matlab to Python, I realised that there was a difference of the order of e-15 in my results. Then I realised that all of this is caused by the exp() functions yielding different results (exp() in Matlab, exp() in Python Math, exp() in Numpy).It seems like a small difference, but this slight difference accumulates over …

The output F is an n-by-1 column vector.. A can also be a function handle, where A(flag,X) must accept an …Nov 24, 2021 · Accepted Answer. Those points at zero show up because alpha is negative and the code is raising alpha to non-integer powers t. For those values of t, alpha^t is complex, and they all have real part equal 0 for those values of t. For example. Then, as the warning states, stem () plots the real part, which is why those zero points show up. Note also that when a<0, the discrete-time exponential signal takes alternating signs. Addition Two Sinusoidal Signal Adding two sinusoids of the same frequency but different amplitudes and phases gives output in another sinusoid (sin or cos) of the same frequency.You didn’t subscript ‘y’ with an index based on the ‘t’ vector.
