statistics: y = unifpdf (x, a, b)

Continuous uniform probability density function (PDF).

For each element of x, compute the probability density function (PDF) of the continuous uniform distribution with parameters a and b, which define the lower and upper bounds of the interval [a, b]. The size of y is the common size of x, a, and b. A scalar input functions as a constant matrix of the same size as the other inputs.

Example: 1

Plot various PDFs from the continuous uniform distribution

 x = 0:0.001:10;
 y1 = unifpdf (x, 2, 5);
 y2 = unifpdf (x, 3, 9);
 plot (x, y1, '-b', x, y2, '-g')
 grid on
 xlim ([0, 10])
 ylim ([0, 0.4])
