Numpy Matrix Ops
Matrix multiplication and dot product.
How it Works
NumPy arrays are C-contiguous maps inside WASM.
Operations run natively using predefined LAPACK functions.
Source Code
Multiplication array pipeline using numpy internally.
import numpy as np
# Create two 3x3 matrices
matrix_A = np.array([
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
])
matrix_B = np.array([
[9, 8, 7],
[6, 5, 4],
[3, 2, 1]
])
print("Matrix A:")
print(matrix_A)
print("\nMatrix B:")
print(matrix_B)
# Matrix Multiplication (Dot Product)
result = np.dot(matrix_A, matrix_B)
print("\nResult of A * B:")
print(result)
# Transpose
print("\nTranspose of Result:")
print(result.T)Matrix A:
[[1 2 3]
[4 5 6]
[7 8 9]]
Matrix B:
[[9 8 7]
[6 5 4]
[3 2 1]]
Result of A * B:
[[ 30 24 18]
[ 84 69 54]
[138 114 90]]
Transpose of Result:
[[ 30 84 138]
[ 24 69 114]
[ 18 54 90]]Real-world Applications
