Matlab symbolic simplify
x^2/6 - (2*x)/15 + 49/15 = 100. When pulling the 100 to the left hand side, we can find the roots: roots([1/6 -2/15 -1451/15]) ans =. 24.4948. -23.6948. where the argument is specified as the prefactors in decreasing order of power. Code with which I found the polynomial (requires the Symbolic Math toolbox): syms x.1. How to stop MATLAB from simplifying symbolic expressions? I am working on a script for log-linearization of non-linear functions, and I need to rewrite such a function into this form: x = z + w -> log(exp(log(x))) = log(exp(log(z)) + exp(log(w)) but MATLAB always automatically simplifies this function into: log(x) = log(z + w) I need to keep ...

The original coefficient vector displays the coefficients as decimals. But when I convert the vector into a symbolic polynomial it turns the coefficients into vector. Is there a way to make the coefficients decimals and not fractionsBecause the symbolic summation is the outermost operation, first apply the rewrite function with the "expandsum" option to expand symsum. Then, apply rewrite again with the "expandroot" option to rewrite the root function.
