Understand the subject
What does it mean to be in a span?
A target lies in a span when it can be made by adding scaled input vectors.
Use it to solve for the coefficients of a requested linear combination.

What the calculation is doing
v₁v₂independent directions span a plane
Worked interpretation
Read the result in context
Ac=v
Interpret with care
Important boundary
A consistent system can have more than one coefficient vector when the input vectors are dependent.
Use the Matrix Calculator to experiment with small exact matrix operations before applying a more specialized route.
Quick guide
How to use this calculator
- Set the matrix dimensions required by the task.
- Fill every visible entry and any operation-specific control.
- Read the result type, factors, classification, and disclosed limitations.
Calculation method
Apply the stated linear-algebra contract
Ac = v
Undefined, singular, dimensionally incompatible, dependent, or unsupported inputs receive an explicit message instead of a fabricated numeric result.
Worked example
Example interpretation
A consistent augmented system proves that v is a linear combination of A’s columns.
Ac = v
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.
