Matrix calculation rules:

• Addition/Subtraction: The matrices must have the same dimensions
• Multiplication: The number of columns in the first matrix must equal the number of rows in the second matrix
• Determinant and Inverse: Only square matrices can be calculated
• Transpose: Swapping rows and columns

Matrix input format:

• Separate numbers by spaces
• Separate rows by commas (;)
• Example: 1 2 3; 4 5 6; 7 8 9
