ParametricFunction
ParametricFunction[pars,…] represents a function that computes a solution when evaluated with numerical values for the parameters pars.
Examples
Evaluate a parametric function with specific parameter values:
pfun = ParametricNDSolveValue[{y'[x] == a y[x], y[0] == 1}, y, {x, 0, 1}, {a}];
pfun[2][0.5]Please visit the official Wolfram Language Reference for more details.
