) integrand=x.^3;Then using the following command, you can evaluate this definite integral as: >> Q=quadl(@myint,-2,6) Q = 320Which is the correct value, that can be verified by calculating: >> 6^4/4-(-2)^4/4 ans = 320Alternatively, we could use an inline function to define our integrand, such as: >> myint=inline('c*exp(j*pi*x)','x','c') myint = Inline function: myint(x,c) = c*exp(j*pi*x)In this case our integrand consists of two variables, c, and the variable of integration, x. To makesure the function quadl knows which variable is the variable of integration we would use the syntax: Q=quadl(@(x)myint(x,2),0,1) Q = 0.0000 + 1.2732iThis command evaluates the integral
