Matrix Inverse

This blog post calculates the inverse of a square matrix with complex numbers.

For the (square) matrix entry, comma separated numbers need to be entered into the Input box, with no newline after the last line. A comma at the end of each line can be added optionally for comma separated numbers. Alternatively, you can load a CSV file into the Input box, by clicking on the Choose File button.

The precision of the results in decimal places can be specified in the text box headed "Precision (decimal places)". To perform the calculation, simply press the button labelled "Perform Matrix Inverse" further down this page. In addition, the matrix size and determinant will be printed.
