DSolveChangeVariables

DSolveChangeVariables[dsolve, u, t, trans] changes the solution function in dsolve to u(t) using the transformation trans.

DSolveChangeVariables[dsolve, {u1, u2, ...}, t, trans] changes the solution functions in the system to {u1(t), ..., un(t)}.

DSolveChangeVariables[dsolve, u, {t1, ..., tn}, trans] changes the solution function in the partial differential equation to u(t1, ..., tn).

Examples

Change variables in a DSolve solution:

DSolveChangeVariables[DSolve[y'[x] == y[x], y, x], u, t, {y -> u, x -> t}]
