tensor

Tensor algebra library in a single header file in C11 for graphics programming, machine and deep learning and physics.

• Vectors, matrices, rank 3 and higher rank tensors.

• Linear algebra and tensor algebra operations.

• Pure C code, easy to integrate in C++ or other languajes using bindings.

• Only one header file.

Take a look at tensor wiki for reading the docs.

Transform vector example

Matrix* matrix = create_indentity(4);
set_value(matrix, 2.0, 0, 3);
set_value(matrix, 3.0, 1, 3);
set_value(matrix, 4.0, 2, 3);

Vector* vector = create_vector(4);
set_value(vector, 1.0, 0);
set_value(vector, 1.0, 1);
set_value(vector, 1.0, 2);
set_value(vector, 1.0, 3);

transform(vector, matrix);
print_vector(vector);

destroy_tensor(matrix);
destroy_tensor(vector);

Inverse of a matrix example

Matrix* matrix = create_indentity(4);
set_value(matrix, 2.0, 0, 3);
set_value(matrix, 3.0, 1, 3);
set_value(matrix, 4.0, 2, 3);

Matrix* inv = inverse(matrix);
matmul(matrix, inv);
print_matrix(matrix);

destroy_tensor(matrix);
destroy_tensor(inv);

Tensor product example

Matrix* A = create_indentity(3);
set_value(A, 3.0, 1, 1);

Matrix* B = create_indentity(2);
product_scalar(B, 2.0);

Tensor* product = tensor_product(A, B);
print_tensor_rank4(product);

destroy_tensor(A);
destroy_tensor(B);
destroy_tensor(product);
