### Function Reference: `plinv`

statistics: data = plinv (p, x, Fx)

Inverse of the piecewise linear distribution (iCDF).

For each element of p, compute the quantile (the inverse of the 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_p size and at least 2-elements long.. The size of data is the same_p as p.

Further information about the piecewise linear distribution can be found at https://en.wikipedia.org/wiki/Piecewise_linear_function

### Example: 1

     ## Plot various iCDFs from the Piecewise linear distribution
     p = 0.001:0.001:0.999;
     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];
     data1 = plinv (p, x1, Fx1);
     data2 = plinv (p, x2, Fx2);
     plot (p, data1, "-b", p, data2, "-g")
     grid on
