Step 1: Create a polynomial function of x and yĮxplanation: As we can see in the output, we have obtained double integral of our input function as 125, which is the same as expected by us. In this example, we will take a polynomial function of x and y. We will follow the following 2 steps:Įxplanation: As we can see in the output, we have obtained double integral of our input function as 5.9161, which is the same as expected by us. In this example, we will take a function of sin with 2 variables ‘x’ and ‘y’. Step 2: Pass the function and required limits to the integral2 functionĮxplanation: As we can see in the output, we have obtained double integral of our input function as 3.9093, which is the same as expected by us. In this example, we will take a function of cos with 2 variables ‘x’ and ‘y’. Let us now understand the code to calculate the double integral in MATLAB using ‘integral2 function’.

These options are passed as paired arguments Examples to Implement Matlab Double Integral

I = integral2 (Func, minX, maxX, minY, maxX, Name, Value) can be used to pass more options to the integral2 function. I = integral2 (Func, minX, maxX, minY, maxY) will integrate the function ‘Func’ (here ‘Func’ is a function of 2 variables X and Y) over the region minX ≤ X ≤ maxX and minY ≤ Y ≤ maxY I = integral2 (Func, minX, maxX, minY, maxX, Name, Value) I = integral2 (Func, minX, maxX, minY, maxY) Let us now understand the syntax of integral2 function in MATLAB: In MATLAB, we use ‘integral2 function’ to get the double integration of a function. In its simplest form, integration for functions with 1 variable is done over a 1-Dimensional space, likewise, integration of functions with 2 variables is done over a 2-D space. In double integral, the integration is performed for functions with 2 variables. Matlab Double Integral is the extension of the definite integral.
