Documentation Help Center. This function is undefined when x and y are zero. Define a function for the upper limit of r. Specify the 'iterated' method and approximately 10 significant digits of accuracy. The function fun must accept two arrays of the same size and return an array of corresponding values.

It must perform element-wise operations. Lower limit of x , specified as a real scalar value that is either finite or infinite. Data Types: double single. Upper limit of x , specified as a real scalar value that is either finite or infinite. Lower limit of y , specified as a real scalar value that is either finite or infinite. You can specify ymin to be a function handle a function of x when integrating over a nonrectangular region. Upper limit of y , specified as a real scalar value that is either finite or infinite.

You also can specify ymax to be a function handle a function of x when integrating over a nonrectangular region. Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1, Absolute error tolerance, specified as the comma-separated pair consisting of 'AbsTol' and a nonnegative real number.

The default value is 1e AbsTol and RelTol work together. For more information on using these tolerances, see the Tips section. Example: 'AbsTol',1e sets the absolute error tolerance to approximately 12 decimal places of accuracy. Relative error tolerance, specified as the comma-separated pair consisting of 'RelTol' and a nonnegative real number. RelTol and AbsTol work together. Example: 'RelTol',1e-9 sets the relative error tolerance to approximately 9 significant digits.

Integration method, specified as the comma-separated pair consisting of 'Method' and one of the methods described below. Example: 'Method','tiled' specifies the tiled integration method. Data Types: char string.

The absolute and relative tolerances provide a way of trading off accuracy and computation time. Usually, the relative tolerance determines the accuracy of the integration.

However if abs q is sufficiently small, the absolute tolerance determines the accuracy of the integration. You should generally specify both absolute and relative tolerances together. The 'iterated' method can be more effective when your function has discontinuities within the integration region.

However, the best performance and accuracy occurs when you split the integral at the points of discontinuity and sum the results of multiple integrations.

When integrating over nonrectangular regions, the best performance and accuracy occurs when ymin , ymax , or both are function handles. Avoid setting integrand function values to zero to integrate over a nonrectangular region.

If you must do this, specify 'iterated' method. Use the 'iterated' method when ymin , ymax , or both are unbounded functions. When paramaterizing anonymous functions, be aware that parameter values persist for the life of the function handle. If you later decide to change the value of a , you must redefine the anonymous function with the new value.

If you are specifying single-precision limits of integration, or if fun returns single-precision results, you might need to specify larger absolute and relative error tolerances.

Evaluate Double Integral in Polar Coordinates. Input Arguments collapse all fun — Integrand function handle. Note AbsTol and RelTol work together.

Note RelTol and AbsTol work together. Integration Method Description 'auto' For most cases, integral2 uses the 'tiled' method. It uses the 'iterated' method when any of the integration limits are infinite.

This is the default method. The integration limits must be finite. The integration limits can be infinite. References [1] L. No, overwrite the modified version Yes. Select a Web Site Choose a web site to get translated content where available and see local events and offers. Select web site.

For most cases, integral2 uses the 'tiled' method.
