Foundational matrix and vector tools in SumWise 3.1
Matrix & Vector Calculator for Windows
Check a small matrix, transpose rows and columns, or count vector entries. Start with the two-by-two determinant below, then use the same Windows workspace for related scientific calculations.

Check a two-by-two determinant
For the matrix with rows [1, 2] and [3, 4], calculate 1 × 4 − 2 × 3.
Copy this expression into SumWise, then press Enter to calculate.
determinant(matrix(2,2,1,2,3,4))Expected result: −2 (a scalar).
The determinant requires a supported square matrix. This is a foundational calculation, not a complete linear-algebra package. Continue with the documented workflow.

Matrix workflows
Build a matrix and work with its structure.
SumWise supports explicit matrix construction and formatted matrix results alongside a focused set of matrix operations.
Transpose a matrix
Exchange rows and columns for a supported matrix value with transpose(...).
Calculate a determinant
Evaluate the determinant of a supported square matrix and keep the result in the calculation workspace.
Vector workflows
Create reusable vectors for calculation and data work.
Construct vectors, count vector entries, and reuse vector values with supported statistics, correlation, and regression functions.
- Construct numerical vectors with
vector(...) - Count vector entries with
length(...) - Assign vectors to variables for later supported calculations
- Use paired vectors in supported correlation and regression workflows
Examples to try
Start with current supported syntax.
These examples exercise documented matrix construction, transpose, determinant, vector construction, and vector entry count.
Enter one expression per calculation. Results are shown separately from copyable input.
matrix(2,2,1,2,3,4)Expected: 2 rows × 2 columns: [1, 2] then [3, 4].
transpose(matrix(2,3,1,2,3,4,5,6))Expected: 3 rows × 2 columns: [1, 4], [2, 5], [3, 6].
determinant(matrix(2,2,1,2,3,4))Expected: −2.
vector(1,2,3,4)Expected: A vector with four entries, in the supplied order.
length(vector(1,2,3,4))Expected: 4 entries. Here length means entry count, not Euclidean magnitude.
A broader Windows math workspace
Keep foundational linear-algebra work beside related calculations.
Students
Practice matrix and vector syntax alongside scientific calculations and supported statistics.
Educators
Show matrix structure, transpose, determinants, and vector entry count with visible inputs and results.
Engineers and developers
Perform quick foundational matrix or vector checks without leaving the desktop math workspace.
Data exploration
Reuse vectors in supported descriptive-statistics, correlation, regression, and scatter-plot workflows.
Honest scope
Foundational operations, not a complete linear-algebra system.
- SumWise supports a focused documented set of matrix and vector workflows.
- This page does not claim comprehensive decomposition, symbolic matrix algebra, or specialist numerical-library coverage.
- Operations retain their documented input-shape and value requirements.

Matrix and vector FAQ
Can SumWise construct and display matrices?
Yes. The documented matrix syntax supplies dimensions and values, and SumWise displays a formatted matrix result.
Can SumWise calculate matrix determinants?
Yes, for supported square matrices. SumWise also supports matrix transpose and other documented foundational operations.
What can I do with vectors?
You can construct vectors, count their entries with length(...), assign them to variables, and use them with supported statistics and regression functions.
Is SumWise a complete linear-algebra package?
No. It provides a practical supported set of foundational matrix and vector operations inside a broader Windows calculator.
A small matrix and vector
Enter matrix(2, 2, 1, 2, 3, 4) to create a two-row, two-column matrix. Enter vector(1,2,3,4) for a four-element vector. Check the function reference before choosing a supported operation; matrix dimensions and vector entry counts matter.
