Here is a list of basic scalar functions in matlab. If solve cannot find a solution and returnconditions is false, the solve function internally calls the numeric solver vpasolve that tries to find a numeric solution. For example, if x is an nbym matrix with n 1, then y is a 1bym row vector containing the rms levels of the columns of x.
