Column Linear Independence Calculator
Column Linear Independence with stated conventions, validation and a worked example.
Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Real matrices only, at most 6 rows and 6 columns; each entry has magnitude at most 10⁹. Numerical rank uses a relative pivot threshold of 10⁻¹² after scaling by the largest entry. Near-singular matrices may be rejected or treated as lower rank. Displayed entries use 12 significant digits.
Example Calculation
- Matrix (vectors as columns): 1, 0; 0, 1
The columns (1,0) and (0,1) are independent.

Frequently asked questions
How do I use this calculator?
Enter matrix (vectors as columns). The result updates automatically. Use Reset to restore the example values.
What method does it use?
Columns are independent exactly when rank equals the number of columns.. Real matrices only, at most 6 rows and 6 columns; each entry has magnitude at most 10⁹. Numerical rank uses a relative pivot threshold of 10⁻¹² after scaling by the largest entry. Near-singular matrices may be rejected or treated as lower rank. Displayed entries use 12 significant digits.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
