e^5=exp (5) in matlab Sign in to comment. MATLAB, like Maple and other mathematical software but in contrast to spreadsheets like Excel, automatically allows and works with complex numbers. so 10e5 does NOT mean 10 to the power of 5 but it means 10 to the power of 6. Use the exponential function exp (y) to compute e^y. In other words, f ( x) drops to zero when , and becomes -1 by the time x reaches pi (see the picture). power of a number in matlab. While you could in theory compute e and then use the power operator ( ^ in matlab) to raise e to that power accordingly, this is in fact a less precise way of calculating the exponential function, and therefore matlab provides the exp function for that purpose. If, for your purposes, it would be sufficient to convert a power of e into a power of 10, then you can just change the base of the exponent: e x = ( 10 log 10 ( e)) x = 10 x log 10 ( e) For example, this is done in the following Matlab code: x = 3. In MATLAB, both i and j denote the square root of -1. [V,D] = eig (A); V*2^D*V^ (-1) ans = 3×3 10. How do you do a power in Matlab. Calculate with arrays that have more rows than fit in memory.
