how to plot the solution of the program in graphical window of scilab?
In "wikipedia" the infinite is defined as something without any bound or larger than any number.But in the computation, the program needs a value to do the calculations. One can not touch or reach infinity but for his own satisfaction he goes to a maximum extent. By using this, one can select a maximum value to solve the given problem. I am considering the 10^25 as the maximum extent for exp(at) where a> 0. With the maximum value we can find the "t" in the following way exp(at) = 10^25, t = 25*log(10)/a. By using this "t" value we can solve the plotting problem. I am writing a simple code about it and hoping that it will be the right answer.
function Exp(a)\n t = 25*log(10)/a\n t = ceil(t)\n time = 0:t/1000:t\n s = poly(0,'s')\n temptf = syslin('c',1/(s+a))\n y = csim('step',time,temptf)\n plot(y,time)\nendfunction
