for an n-dimensional vector x, the function should return another vector 2n-dimension which each element is repeated twice.
in->[2 3 NaN 5] and out->[2 2 3 3 NaN NaN 5 5]
improve test suit
This solution only works for vectors that are already sorted from low to high :) but it passed the test suite
This works in R2012b, but not on cody
function ans = duplicate(x)
Select every other element of a vector
Swap the input arguments
Compute a dot product of two vectors x and y
Celsius to Kelvin
Sum the 'edge' values of a matrix
Matrix with different incremental runs
First non-zero element in each column
vectorization in N
Matrix which contains the values of an other matrix A at the given locations.
Create a matrix X, where each column is a shifted copy of the vector v
