Using sympy to substitute "number values" into the entries of a 10X10 matrix (in python)
<p>I'm using the symbolic package sympy to store a 10X10 antisymmetric matrix in terms of 10 variables. and then at every iteration step, i substitute numerical values into the entries of the matrix. however, it's taking too long to substitute values because the symbolic expressions are very complicated. It takes around 100 seconds for the every substitution and I need at least 10,000 iterations to get a meaningful result. </p>

<p>So, I was wondering whether there is any speedy way to substitute the values. Right now, I'm just substituting values into the top diagonal half of the matrix, which halves the number of substitutions, but it's still taking too long. </p>

<p>Thanks!</p>
