Witryna16 lis 2024 · Powers already exist in MATLAB so there is no need for a loginv function. (I suppose it might be nice for completeness to have that, but you can always write a loginv function yourself, if that "lack" bothers you.) 10^x is an error, BECAUSE x is not a scalar. If you need to exponentiate an array or a vector, then use 10.^x.
