MATLAB: Is @(x) used in matlab and how does it work

MATLABpdfrandom variable

pdfx = @(x) 2*sqrt(x);          % Define PDF
x = rand(1,100000);             % Generate Random ‘x’
px = pdfx(x);                   % Generate Data
This is a piece of code used to generate a random variable of self defined pdf. Why is @(x) used here and how is it working.

Its creates the function handle, I suggest ti go through the following MATLAB Documentation, and any issue let us know here
https://www.mathworks.com/help/matlab/matlab_prog/creating-a-function-handle.html
1.See the example, the first line cretes the function named as "pdfx" (Function is 2*sqrt(x))
pdfx = @(x) 2*sqrt(x);
2. Next you have defined x some random data
x = rand(1,100000);             % Generate Random ‘x’
3. Passing the x values in the function pdfx as defined 
px = pdfx(x);
Its similar to, defined the function file 
function y=pdfx(x)
y =2*sqrt(x);
end
Now call the function 
x = rand(1,100000);    
px = pdfx(x);

Experts any comments please (If I missed any important issue)
