plcdf
"upper")Piecewise linear cumulative distribution function (CDF).
For each element of data, compute the cumulative distribution function (CDF) of the piecewise linear distribution with a vector of x values at which the CDF changes slope and a vector of CDF values Fx that correspond to each value in x. Both x and Fx must be vectors of the same size and at least 2-elements long. The size of p is the same as data.
p = plcdf (data, x, Fx, "upper") computes
the upper tail probability of the piecewise linear distribution with
parameters x and Fx, at the values in data.

## Plot various CDFs from the Piecewise linear distribution
data = 0:0.01:10;
x1 = [0, 1, 3, 4, 7, 10];
Fx1 = [0, 0.2, 0.5, 0.6, 0.7, 1];
x2 = [0, 2, 5, 6, 7, 8];
Fx2 = [0, 0.1, 0.3, 0.6, 0.9, 1];
p1 = plcdf (data, x1, Fx1);
p2 = plcdf (data, x2, Fx2);
plot (data, p1, "-b", data, p2, "g")
