Solve Problems with Gaussian Random Matrix: Compressed Sensing Senior Project

[giaoduong]

I'm doing my senior project about Compressed sensing, I have some problems with some algorithms.
1)Can anybody help me about Gaussian random matrix, how we can explain it briefly.
2)Does the randn(m,n) building function in Matlab working bases on Probability density function? How does randn work?

Please help me!

Thank you!
Have a nice day!
