You can verify that by calling null(full(A)) on an example matrix (I used Nx = Ny = 10, dx = dy = 0.1). This showed that there is a null space of dimension one, and the vector in that null space had all elements of equal value.

Remember that in Python, an index of -1 means the last value on that dimension. Then you are printing arr_1 to verify that the lower right value has changed from 9 to 42. Finally, you are printing arr_2, and you see for arr_2 as well, the bottom right value has changed from 9...
Identity matrices are fundamental to linear algebra and matrix operations. Excel has a dedicated function namedMUNIT functionthat creates an identity matrix of a given dimension. What is a determinant? The determinant is a special scalar value computed from a square matrix that provides crucial inform...
Where $a_i$ and $b_i$ are the $i$-th elements of vectorsaandbrespectively, and $n$ is the dimension of the vectors. In other words, to calculate the dot product, we multiply the corresponding elements of the two vectors and sum up the results. The dot product results in a scalar...
