My program is suppose to change 12 zeros on random positions to 1 in python 6×6 matrix. This is my code. So my matrix is going to look like this at the beggining So I randomly chose an array and the element in chosen array. The problem is that different number of zeros is changed every time. Not 12 like

Iterate through an adjacency matrix with a list
So I have a n x n adjacency matrix, N x N NumPy array, where the i-th row and the j-th column is the distance between the i-th and j-th cities. I also have list, in a specific order in which I have to visit the cities and and add the distances together. The list items are pointing to row/column
How to change pixel value based on a condition
The image is 1920 by 1080. How can I change the value of a pixel when a channel value is higher than the other? Here is what I did. Is there a more efficient way than iterating on each pixel? Answer Don’t use any loop for this, use ndarray capability and logical indexing. What you want to achieve is som…

Check if any element of a list is in a matrix?
I have a small list: and I have a matrix too. for example: And I need to determine if any of the elements of l ist2 of this array are not in the matrix2. I try to use np.isin() : But this code only shows if there is the elements in the matrix or not completely. But I need this
Numpy matrix creation timing oddity
My application requires a starting matrix where each column is staggered-by-1 from the previous. It will contain millions of complex numbers representing a signal, but a small example is: I tried two creation methods, one fast, one slow. I don’t understand why the fast matrix creation method causes subs…
