WebThe MATLAB functions log1p and expm1 calculate log ( 1 + x) and e x - 1 accurately for very small values of x. For example, if you try to add a number smaller than machine precision to 1, then the result gets rounded to 1. log (1+eps/2) ans = 0 However, log1p is able to return a more accurate answer. log1p (eps/2) ans = 1.1102e-16 http://www.ece.northwestern.edu/local-apps/matlabhelp/techdoc/ref/isnan.html

WebNaN values in a vector are treated as different unique elements. For example, unique ( [1 1 NaN NaN]) returns the row vector [1 NaN NaN]. Use the isnan or ismissing function to detect NaN values in an array. Use the anynan or anymissing function to determine if any array element is NaN.
