Purpose of the determinant of inverse matrix template
This Python template automates the calculation of a 4x4 matrix inverse and computes key linear algebra metrics using Python. It serves as a practical demonstration of how to determine the inverse of a matrix using NumPy within the Quadratic Python spreadsheet.
By processing raw data through Python code cells, the template:
- Provides immediate feedback on matrix invertibility and eigenvalues.
- Demonstrates Python-based linear algebra workflows in a spreadsheet interface.
Inputting matrix data
Users begin by locating the designated input workspace in cells A3:D6. This area is clearly marked by a descriptive label in cell A2 to verify the active input location.
To prepare the data for analysis:
- Enter raw numerical values to populate the 4x4 grid.
- Ensure the matrix remains square to allow for valid determinant calculations.
Python logic and calculation flow
Matrix_Inverse code cell
This code cell reads user-defined values directly from the input range A3:D6. It applies NumPy linear algebra functions to compute the inverse and handles the necessary mathematical operations required to find the inverse of a matrix determinant. The cell automatically recalculates whenever input values change.
Matrix_Analysis code cell
The analysis cell performs a comprehensive scan of the source matrix to derive deeper insights. It calculates the determinant of an inverse matrix alongside the original determinant to provide a complete picture of the matrix's properties.
Key functions performed by this cell include:
- Verifying if the matrix is invertible by returning a boolean value.
- Computing all four eigenvalues for the 4x4 dataset.
Understanding the analysis outputs
Inverse matrix results
The template outputs the calculated inverse matrix to the range A9:D14. This section includes generic column headers (c1 through c4) for easy referencing by other cells and updates dynamically based on the invertibility of the source data.
Analytical metrics table
A summary table in range F9:G19 displays the core analytical data. It lists the source range and matrix shape dimensions for verification.
The table structures the results as follows:
- Shows the determinant and inverse of a matrix in a two-column format.
- Provides specific eigenvalue results derived from the input.
