Combinations from range of values for given sizes

Question

I\'m using the following code to create a list of indices for an array. However, I would like the index to run in Fortran order i.e. the inner loop being the faster varying

Answer 1

Is this what you are after?

a = np.transpose(np.nonzero(np.ones([32,30])))  
a.reshape(32,30,2).transpose(1,0,2).reshape(-1,2)
Out[2197]: 
array([[ 0,  0],
       [ 1,  0],
       [ 2,  0],
       ..., 
       [29, 29],
       [30, 29],
       [31, 29]], dtype=int64)
