22.05.2017 · Accepted Answer: Star Strider. I want to use the symbolic function `int` to find the indefinite integral of the function 4*x^2+3, and the definite integral from x = -1 to x = 3. here is my approach, but got an error: int (4*x^2+3) int (4*x^2+3, x = …

For definite integrals, int restricts the integration variable var to the specified integration interval. If one or both integration bounds a and b are not numeric, int assumes that a <= b unless you explicitly specify otherwise.

uses the symbolic object v as the variable of integration, rather than the variable determined by symvar . See how int works by looking at this table.

When int cannot compute the value of a definite integral, numerically approximate the integral by using vpa. syms x f = cos (x)/sqrt (1 + x^2); Fint = int (f,x, [0 10]) Fint =. Fvpa = vpa (Fint) Fvpa =. To approximate integrals directly, use vpaintegral instead of vpa.

Find the indefinite integrals of the multivariate expression with respect to the variables x and z. Fx = int (f,x) Fx (x, z) =. x 2 2 z 2 + 1. Fz = int (f,z) Fz (x, z) = x atan ( z) If you do not specify the integration variable, then int uses the first variable returned by symvar as the integration variable. var = symvar (f,1) var = x.
