MATLAB: Why step size is divided by 50

matlab/simulink

step size = (Tmax-Tmin)/50
my question is why it should divided by 50?

HI SK, Let say you have a function f (t) and you want to plot it between t = Tmin and Tmax, in matlab, you have to choose a step size to do so. The step size is defined as delta = (Tmax-Tmin)/(N-1), This is exactly what the function linspace does. The following are equivalent :
N = 51;
stepsize = (Tmax-Tmin)/50;
t = Tmin:stepsize:Tmax;
t = linspace (Tmin, Tmax, 50);
