Discretize sphere into 3xN points

I need to discretize a sphere into 3xN points. I know the sphere function in Matlab will generate points, but it generates the X, Y, Z coordinates as matrices. I don't really understand how these matrices work to convert them into a list of 3XN cartesian coordinates. Thanks

Then sphere is not the best point to start. Do you have any specifications for discretization? Do you want radom point, equi-distributed points, or do you have a specific set of values for N?

I have a specified radius and centre. Being able to specify a set value of N would be nice but not necessary.

I just used the mysphere function and multiplied by the radius, added the centre. Thanks.
