What is the GAMMA function in MATLAB?

In MATLAB, the GAMMA function is an implementation of the gamma function. The gamma function, represented by the symbol “Γ,” is a special mathematical function that is highly useful in fields such as statistics, probability theory, physics, and engineering.

The definition of the Gamma function is as follows:

$$
\Gamma(z) = \int_0^{\infty} t^{z-1} e^{-t} dt
$$

In this case, z is a parameter that can be either a complex number or a real number.

In MATLAB, you can use the `gamma` function to calculate the value of the gamma function. For example, to calculate the value of the gamma function with a parameter of 2, you can use the following code:

x = 2;
y = gamma(x);

At this point, the variable `y` will hold the result of the gamma function. It is important to note that the `gamma` function in MATLAB also supports vectors and matrices as input parameters.
