WebThe integration bounds are an iterable object: either a list of constant bounds, or a list of functions for the non-constant integration bounds. The order of integration (and therefore the bounds) is from the innermost integral to the outermost one. The integral from above. I n = ∫ 0 ∞ ∫ 1 ∞ e − x t t n d t d x = 1 n. WebFunction to evaluate, specified as a function name or a handle to a function. The function accepts M input arguments, and returns N output arguments. To specify fun as a function name, do not include path information. Invoking feval with a function handle is equivalent to invoking the function handle directly. Example: fun = 'cos'.
