Hello, When I express symbolic expressions using syms with decimal values, I often get very large fractions. Since the result is not constant, I cannot use double() to evaluate the result as a decimal. sym2poly() works in most cases, but one day I will probably need to evaluate a long expression that is not a polynomial ...Simplify expressions involving exponents and logarithms. In the third expression, use log(sym(3)) instead of log(3).If you use log(3), then MATLAB ® calculates log(3) with the double precision, and then converts the result to a symbolic number.ans =. z^3 - (3*z^2)/2 + 1/4. If the second argument is a number, euler evaluates the polynomial at that number. Here, the result is a floating-point number because the input arguments are not symbolic numbers: euler(2, 1/3) ans =. -0.2222. To get the exact symbolic result, convert at least one number to a symbolic object:This MATLAB function performs algebraic simplification of expr. In most cases, to simplify a symbolic expression using Symbolic Math Toolbox™, you only need to use the simplify function.By default, simplify only sums or averages the edge weights in the graph and drops all other edge properties. However, you can use the 'AggregationVariables' name-value pair to specify which numeric variables in G.Edges to preserve and aggregate.The Jacobian of a vector function is a matrix of the partial derivatives of that function.
