Can anyone solve the following Meijer-G function in matlab for any numerical value of z, k, Q1 and Q2?
Thanks in advance for your help

can anyone explain,how those vectors 2,1,1,3 have used?

For
The a (top) vector is of length p. So for the top vector is of total length 1.
The b (bottom) vector is of length q. So for the bottom vector is of total length 3
In the overall computation of the function, the first m elements of the b (bottom) vector are used in the numerator in the form "element minus s" (s is the variable of integration). So for the first two elements of the b (bottom) vector are used in that form, leaving = 3-2 = 1 element of b unused for that particular purpose.
In the overall computation of the function, the first n elements of the a (top) vector are used in the numerator in the form "s + 1 minus element" (s is the variable of integration). So for the first 1 element of the a (top) vector are used in that form, leaving =1-1 = 0 elements of a unused for that particular purpose.
In the overall computation of the function, the remaining elements of b are used in the denominator in the form "s + 1 minus element" (s is the variable of integration). So for then 3-2 = 1 element of b is used that way.
In the overall computation of the function, the remaining elements of aare used in the denoninator in the form "element minus s" (s is the variable of integration). So for it would be 1-1 = 0 elements of a that are used that way.
MATLAB's meijerg() function uses the syntax . In this case A corresponds to the first n elements of the top vector of the notation, and the value n is implied as length(A). B corresponds to the remaining elements of the top vector of the G notation, and the value p is implied as length(A)+length(B) . C corresponds the the first m elements of the bottom vector of the G notation, and the value m is implied as length(C ) . D corresponds to the remaining elements of the bottom vector of the G notation, and the value q is implied as length(C )+length(D)

How do I calculate the Meijer G function using matlab ( | |x|^2) where the first row vector is $(1/2-a , -a)$ and the second row is $(0 , -1/2)$ where $a>0$ and less than $1/2$ and $|x|>1.$
