Pure frontend matrix calculator with exact rational arithmetic. Supports common linear algebra operations and step-by-step RREF.
- Exact fractions (integer / fraction / decimal input)
- A + B, A - B, A x B, transpose, determinant, inverse, adjugate, rank, power
- Solve linear system A x = b
- RREF for A and augmented (A|B)
- Markdown + LaTeX rendering (MathJax)
- LaTeX output copy
Open index.html in a browser, input matrices, choose an operation, and click 计算.
Input format:
- Rows separated by newlines or semicolons
- Columns separated by spaces or commas
- Supports integers, fractions (e.g.
3/4), and decimals (e.g.0.125)
- Math rendering uses CDN (MathJax + markdown-it), so internet is required for formulas.
- For large matrices, exact fractions may grow quickly and become slow.
纯前端矩阵计算器,使用精确分数计算,支持常见线性代数运算与 RREF 步骤展示。
- 精确分数(支持整数 / 分数 / 小数输入)
- A + B、A - B、A x B、转置、行列式、逆矩阵、伴随矩阵、秩、幂
- 解线性方程组 A x = b
- A 的行最简式(RREF)与增广矩阵 (A|B) 的行最简式
- Markdown + LaTeX 渲染(MathJax)
- LaTeX 输出复制
直接在浏览器中打开 index.html,输入矩阵,选择运算并点击 计算。
输入格式:
- 行用换行或分号分隔
- 列用空格或逗号分隔
- 支持整数、分数(例如
3/4)、小数(例如0.125)
- 公式渲染依赖 CDN(MathJax + markdown-it),需要联网。
- 大矩阵可能导致分数膨胀,计算会变慢。
