SimpleArray = [1,0,2,0,3,0,4,0,5,0]
Desired result
NewSimpleArray = [1,2,3,4,5]

Here is a good solution:
NewSimpleArray = SimpleArray(SimpleArray ~= 0)

SimpleArray(SimpleArray==0) = [];

Thanks for the answers and for showing me the previous discussion string (I didn't think this was the first time this question was asked)

Using nonzeros is also very simple (note that the output is a column vector):
NewSimpleArray = nonzeros(SimpleArray)
NewSimpleArray =
1
2
3
4
5

That changes the shape from a row vector to a column vector. However it can be fixed with the code below:
SimpleArray = [1,0,2,0,3,0,4,0,5,0] % Row Vector
NewSimpleArray = nonzeros(SimpleArray) % Creates column vector.
% Reshape back into a row vector.
NewSimpleArray = reshape(NewSimpleArray, 1, [])

Simply by:
X(X==0)=[]
