WebY = log (X) returns the natural logarithm ln (x) of each element in array X. The log function’s domain includes negative and complex numbers, which can lead to unexpected results if … WebWorking Together. Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same): They are "Inverse Functions". Doing one, then the other, gets us back to where we started: Doing ax then loga gives us back x: loga(ax) = x. Doing loga then ax gives us back x: aloga(x) = x.
