Normal Distribution

IMPORTANT Some of these functions require the Statistics and Machine Learning to work. Make sure it is installed before trying to use them.

Normal Distribution Operations

solve(eqn1,eqn2,var1,var2) solves a or a system of symbolic equations. The equations can be inputted in a matrix or separately and so can the variables that you desire to solve for. Full Documentation
```
  syms x
  eq1 = 4*x^2 + 8 == -4;
  solve(eq1,x)
```
```
  syms x y;
  eq1 = x + y - 5 == 0;
  eq2 = x^2 - y == 3;
  [xsol ysol] = solve(eq1,eq2,x,y)  
```
normpdf(x,mu,sigma) calculates the y values over a range of x values with a normal distribution model of mean mu and standard deviation sigma.Full Documentation
```
  x = [0:0.2:10];
  y = normpdf(x,5,2);
  plot(x,y)
```
