The function requires two inputs for the endpoints of the output vector...11 Feb 2022 ... x(t) = t.*(exp(-0.15*t));. Array indices must be positive integers or logical values.Mar 27, 2015 · Therefore, using your x and y values, this is what I get: A = 1.3882 b = -11.508. If we plot the above points as well as an exponential curve that fits the line, we can do: xval = linspace (min (x), max (x)); yval = A*exp (b*xval); plot (x,y,'r.',xval,yval,'b'); The first line of code defines a bunch of x values that span between the smallest ... this finds the maximum absolute exponent, and returns that. So if A = [1e-6 1e20], it will return 20. I'm actually not sure quite how Matlab decides what exponent to use when printing out. Obviously, if A is close to 1 (e.g. A = [100, 203]) then it won't use an exponent at all but this solution will return 2. You'd have to play around with it a ...Matlab has a function called polyfit. It can fit curve to a data which can be represented in the form a*X^n+b*X^(n-1)+.....z. However if you are sure that the data is of some exponential decay you can try taking logarithm …1 Mar 2007 ... Abstract. Recently, a great deal of attention has been focused on the construction of exponential integrators for semilinear problems. In this ....
