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. Also, I am very reluctant to hard-coding of my integration upper limit, as you suggest. Is 20 enough?

decimal notation NaN f ork. NaN; fork. for Not a Number. ett resultat av en odefinierad operation.

5 How can I make MATLAB use the full window width for displaying matrices? 6 How do I comment out a large block of code?

Programmering med Matlab - Smakprov

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.

Y = log10(X) Description. The log10 function operates element-by-element on arrays. Its domain includes complex numbers, which may lead to unexpected results if used unintentionally. Y = log10(X) returns the base 10 logarithm of the elements of X. Examples.
