Hi Hemvarshan,

I understand that you want to convert the above expression into MATLAB Code.

From the code it seems that you are using advanced mathematical functions like gamma functions. You can always leverage MATLAB Documentaion to search for syntax, function code and relevant examples for such functions.

Consider an example below:

To evaluate the expression Γ(0.5), you can use the following MATLAB code:

y = gamma(0.5)

Similarly, you can convert the complete expression into code. You can also use functions to avoid code repetition.

[Walter Roberson]

Note: there are two different gamma() functions that are important for this purpose

which gamma(0.5)

built-in (/MATLAB/toolbox/matlab/specfun/@double/gamma)  % double method

which gamma(sym(0.5))

/MATLAB/toolbox/symbolic/symbolic/@sym/gamma.m  % sym method

So if you pass in a double precision number, the double-precision gamma() function will be used. That is a completely different code path than if gamma is invoked on a symbolic expression of any kind

gamma(0.5)

ans = 1.7725

gamma(sym(0.5))

ans = 

When you are working with MeijerG functions and so on, you will certainly want to be working with the symbolic version
