How can make a dataset of elements of matrices in dataframe?

Question

I have dataset of 3 parameters \'A\',\'B\',\'C\' in .TXT file and after I print them in 24x20 matrices I need to collect

Answer 1

I am not sure if I understood your question fully but this is a solution:

Convert your data frame to a 2d numpy array using as_matrix() then use ravel() to get a vector of size 480 * 3 then cycle over your cycles and use vstack method for stacking rows over each other in your result, this is a code with your example data:

A = [[1,2,3,4], [10,20,30,40]]
B = [[4,5,6,7], [40,50,60,70]]
C = [[8,9,10,11], [80,90,100,110]]

cycles = 2

for cycle in range(cycles):
    data = {'A': A[cycle], 'B': B[cycle], 'C': C[cycle]}
    df = pd.DataFrame(data)
    D = df.as_matrix().ravel()
    if cycle == 0:
        Results = np.array(D)
    else:
        Results = np.vstack((Results, D2))
# Output: Results= array([[  1,   4,   8,   2,   5,   9,   3,   6,  10,   4,   7,  11], [ 10,  40,  80,  20,  50,  90,  30,  60, 100,  40,  70, 110]], dtype=int64)
np.savetxt("Results.csv", Results, delimiter=",")

Is this what you wanted?
