Elementary Row Operation Tester for Matrix\n\noriginally created for inspecting the mistakes in Linear Algebra course done by students.\n\nit is inspired by [Jello](https://www.youtube.com/watch?v=tNaZykHHHWs) and Jupyter notebook.\n\n\n## Usage\n\nopen a file like `ops.txt` and then run the app by `app ops.txt`, here's the example content for `ops.txt`:\n\n```\n3 7 5 6\n1 3 3 -2\n0 1 4 -4\n\nr2 += -3r3\nr1 += 3r2\nr1 \u003c\u003e r2\nr2 += -7/4r3\nr3 \u003c\u003e r2\n\n?\n```\n\nthe app watches for changes in the `ops.txt` and reruns when new modification detected\n\n## Operations\n- `r1 += -3/2r1`: assigns row 1 as `r1 + -(3/2).r2` here `3/2` is rational i.e. $\\frac{3}{2}$\n- `r1 *= 3`: scales row 1 by 3\n- `r1 \u003c\u003e r2`: swapes row 1 and row 2\n- `?`: prints matrix so far\n- `t`: transpose\n- `mx`: mirror to the y axis\n- `my`: mirror to the x axis\n- `1 2 ...`: add the row `1 2 ...` to the matrix\n\n\n## Features\n- [x] support rational numbers\n\n## Limitations\n- [ ] cannot use floating point numbers, it must be represented in rational form.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhamidb80%2Felementary-row-operations","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhamidb80%2Felementary-row-operations","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhamidb80%2Felementary-row-operations/lists"}
