Matlab Program for exponential wave

Brief TheoryIn Exponential Wave, the amplitude varies exponentially with respect to time. Exponential Wave is expressed as y=a*exp(b*t) where a is a constant and b is the amplitude and t is the time. Exponential wave may be positive or negative exponential according to the amplitude. If amplitude is positive it is positive...
