## tauvolt

Tau Volterra evaluation.

Tau Volterra evaluation.

[v, f] = tauvolt(step, x, fun, Kxt)

Evaluates the Volterra integral term from an approximated function.

step = evaluation step (double). x = independent tau variable (itau object). fun = function f(x) (char or double vector). Kxt = function F(x,t) (char).

v = v(x). f = coefficients for the approximation int_a^x(fun(t)*K(x, t))dt.

x = itau('LegendreP', [0 1], 5); [v, f] = tauvolt(0.1, x, ''x^2-3*x+1'', 'cos(x+t)'); or: x = itau('LegendreP', [0 1], 5); [v, f] = tauvolt(0.1, x, [-1/6 -1 1/6]', 'cos(x+t)'); In the first example the function is interpolated by orthogonal basis whereas in the second the coefficients are already provided.
