MATLAB is a math software package with many built-in functions. You can create your NaN represents the value Not-a-Number. numden returns plot(w/pi,20* log10(abs(H))); grid; title('Magnitude Response in dB of LPF');.

Teach with MATLAB and Simulink Ready-to-use courseware, code examples, and projects. Get started . Get a Trial of MATLAB and Simulink Products If X is a vector, then nansum(X) is the sum of all the non-NaN elements of X.. If X is a matrix, then nansum(X) is a row vector of column sums, computed after removing NaN values.. If X is a multidimensional array, then nansum operates along the first nonsingleton dimension of X.The size of this dimension becomes 1 while the sizes of all other dimensions remain the same. Y = log10(X) returns the common logarithm of each element in array X. The function accepts both real and complex inputs. For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf,Inf). For complex and negative real values of X, the log10 function returns complex values.

The log10 function operates element-by-element on arrays. Its domain includes complex numbers, which may lead to unexpected results if used unintentionally.

This is the second of the indeterminant forms listed in this section of the Wikipedia page for NaN. $\begingroup$ Of course I understand that Matlab does not simplify $\log(\exp(-x))$ for me. But I've defined a function g precisely to avoid NaNs caused by $\log 0$ or $0\log 0$, so I'm puzzled as to what causes the NaNs.

MATLAB preserves the “Not a Number” status of alternate NaN representations and treats all of the different representations of NaN equivalently. However, in some special cases (perhaps due to hardware limitations), MATLAB does not preserve the exact bit pattern of alternate NaN representations throughout an entire calculation, and instead uses the canonical NaN bit pattern defined above. MATLAB ® preserves the "not a number" status of alternate NaN representations and treats all representations equivalently. In some special cases, due to hardware limitations for example, MATLAB does not preserve the exact bit pattern of the alternate representations during computation, and instead uses the canonical NaN bit pattern previously Y = log10(X) Description.

If X is a vector, then nanmean(X) is the mean of all the non-NaN elements of X.. If X is a matrix, then nanmean(X) is a row vector of column means, computed after removing NaN values..
