What are basis and dimension?

A basis is a smallest independent set that can build every vector in a span. Dimension is the number of basis directions.

Use it to remove redundant vectors without changing the span.

What the calculation is doing

Worked interpretation

Read the result in context

dimension(span)=rank

Interpret with care

Important boundary

A long input list can still span a low-dimensional space.

Use the Matrix Calculator to experiment with small exact matrix operations before applying a more specialized route.

Quick guide

How to use this calculator

  1. Set the matrix dimensions required by the task.
  2. Fill every visible entry and any operation-specific control.
  3. Read the result type, factors, classification, and disclosed limitations.

Calculation method

Apply the stated linear-algebra contract

dimension(span{v₁,…,vₖ}) = rank([v₁ … vₖ])

Undefined, singular, dimensionally incompatible, dependent, or unsupported inputs receive an explicit message instead of a fabricated numeric result.

Worked example

Example interpretation

Dependent input vectors are omitted from the returned basis.

dimension(span{v₁,…,vₖ}) = rank([v₁ … vₖ])

Supported inputs

Precision and limits

Matrix size

Input matrices are limited to 1–6 rows and columns; operation-specific square, rank, or compatibility rules still apply.

Entry precision

Enter signed finite decimals with at most 30 digits and 15 decimal places.

Exactness

Finite decimals become reduced rational numbers and intermediate structural calculations are not rounded.
