Hi Ujjal,

In your case you have to numerically evaluate an integral of a 4-variable function. Mathworks provides built-in functions for 1, 2 or 3 variables (e.g. integral3 ). In your case you could use something from the Mathworks Exchange Central e.g. the 4-variable function - NUMERICAL INTEGRATION
