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.
The key function in Matlab to create a symbolic representation of data is: syms ... expand(S): Multiples out all the portions of the expression or equation.
Expand only algebraic expressions, specified as the comma-separated pair consisting of 'ArithmeticOnly' and true or false. If the value is true, the function expands the arithmetic part of an expression without expanding trigonometric, hyperbolic, logarithmic, and special functions. This option does not prevent the expansion of powers and roots.

Defining Symbolic Expressions We can define symbolic functions using the sym command and syms command. Here is an example of creating a symbolic function for (a*X^2) + (b*x) + c: >> syms a b c x % define symbolic math variables >> f = sym('a*x^2 + b*x + c'); From now on we can use the f symbol to represent the given function.
This MATLAB function multiplies all parentheses in S, and simplifies inputs to functions such as cos(x + y) by applying standard identities. Skip to content. ... Expand Symbolic Expression. syms x p = (x - 2)*(x - 4); expand(p) ans = x^2 - 6*x + 8. Expand Trigonometric Expression.
expand (S) multiplies all parentheses in S, and simplifies inputs to functions such as cos (x + y) by applying standard identities. expand (S,Name,Value) uses additional options specified by one or more name-value pair arguments. For example, specifying 'IgnoreAnalyticConstraints' as true uses convenient identities to simplify the input.
Dec 05, 2018 · I wonder if there is any way to prevent MATLAB from expanding the matrix symbolic expression? For example, let's A = 3x3 matrix and b = constant. Desired output:
