MATLAB quad and difficulty with vector input

Click For Summary
SUMMARY

The forum discussion centers on the use of the MATLAB function "quad" for numerical integration with vector inputs. The user encounters a matrix dimension error when attempting to integrate a function that includes a vector parameter 'a'. The solution proposed involves switching from "quad" to "quadv", which is designed to handle vectorized inputs more effectively. This change resolves the issue and allows for successful integration over the specified range.

PREREQUISITES
  • Understanding of MATLAB function syntax and usage
  • Familiarity with numerical integration methods in MATLAB

MATLAB "quad" and difficulty with vector input

Hello all.

Consider the following:

function y = testf(x,a)
y = sin(pi.*a.*x);

...and then we have

a = 0.05:0.05:1;
result1 = quad(@(x)testf(x, a),0,1)

which crashes with

? Error using ==> times
Matrix dimensions must agree.

Can you help?
Thank you.

Oops. Is this just a matter of using quadv instead of quad?
