So Im wondering if you can suggest any tools, free or paid, that will be great. Integer, etc.., strings are also converted to SymPy expressions. SymPy is an open-source Python library for symbolic computation. x!). dot (v_2) # whereas this gives the scalar directly \[c e + d f\] Similarly, the outer product \(\mathbf{v}_1 \mathbf{v}_2^T\) of two column vectors can be computed via. By default it will return conditions of convergence as well (recall this is an improper integral, with an infinite bound, so it will not always converge). When I say "solution", I mean either from outside LaTeX (i.e: an external program that makes the conversion and outputs LaTeX syntax), or from within LaTeX (i.e: some package that takes C-like math and displays it in formula format on-the-fly). From the File menu, select Export As. SymPy is simple to install and to inspect because it is written entirely in Python with few dependencies. In this step … SymPy is a Python library for symbolic mathematics. In [3]: # Following is an Ipython magic command that puts figures in the notebook. Specify a path and folder for the file.
