Define a function that restricts input to a numeric vector that contains noInforNaNelements. function[m,s] = stat3(x)argumentsx(1,:) {mustBeNumeric, mustBeFinite}endn = length(x); m = avg(x,n); s = sqrt(sum((x-m).^2/n));endfunctionm = avg(x,n) m = sum(x)/n;end ...
The function is a local function within a function file, and any local function in the file uses theendkeyword. The function is a local function within a script file. example Examples collapse all Function with One Output Define a function in a file namedcalculateAverage.mthat accepts an input...
