Computing: Free Pascal Programming

Mathematics: Determinant calculation.

Download Determinants desktop application (Windows 64bit) Download Determinants source code (Lazarus/Free Pascal)

Description: Calculation of 2x2, 3x3 and 4x4 determinants with display of the expansion minors, just as if you calculated the determinant by hand. Choose the size of the determinant in the File menu. 2x2 determinant calculation is done in the main window, for higher sizes, a new window opens. Enter the determinant's values and push Calculate. For 4x4 determinants, only the 3x3 expansion minors are displayed; you can however expand any of these (with display of its 2x2 minors) by pushing the corresponding Expand |Dn| button.

Free Pascal features: Basic controls. Shapes. Multiple forms (each of them containing its own code to do a specific task). Multi-dimensional arrays (classic Pascal).
