Convert numeric values to symbolic numbers or expressions. Use sym on subexpressions instead of the entire expression for better accuracy. Using sym on entire expressions is inaccurate because MATLAB first converts the expression to a floating-point number, which loses accuracy. sym cannot always recover this lost accuracy.
Cell to String MATLAB Introduction to Cell to String MATLAB There are two commands used to covet cell data into string format one is char and the other is a string. char and string commands extract all the data from cell arrays and stored in the form of string. In Matlab, we use string notations as data in single or double quotes ( “ ” or ‘ ‘ ).
26.09.2013 · Converting sym to string without... Learn more about symbolic, strings MATLAB, Symbolic Math Toolbox. Skip to content. ... Caution: char() of a symbolic expression gives a result which is not exactly a MATLAB expression, and which is not exactly a MuPAD expression either.
sym (strnum) converts the character vector or string specified by strnum to an accurate symbolic number that avoids any approximation. example symexpr = sym (h) creates a symbolic expression or matrix symexpr from an anonymous MATLAB function associated with the function handle h. Examples collapse all Create Symbolic Variables
17.10.2021 · syms x y. eqn = x^2+2*x*y+3*y^2; partial_eqn = diff (eqn, x); fprintf ("The partial derivative of %s w.r.t. x is %s \n", string (eqn), string (partial_eqn)) The partial derivative of 2*x*y + x^2 + 3*y^2 w.r.t. x is 2*x + 2*y. Also, using fprintf is easier and creates a more pleasing result. . Sign in to answer this question.
String representing a symbolic formula, specified as a character vector, string scalar, cell array of character vectors, or string array. You can also combine a string that represents a symbolic formula with regular text (enclosed in single quotation marks) as a string array. For an example, see Display Differential Equation.
Jul 23, 2017 · Commented: Walter Roberson on 2 Jun 2021. Accepted Answer: Walter Roberson. I have very long arrays of symbolic variables which I need to convert to cell arrays of strings: For example, turning this: syms x y u. q = [x y u] into this: qs = {'x' 'y' 'u'}
Sep 26, 2013 · Caution: char () of a symbolic expression gives a result which is not exactly a MATLAB expression, and which is not exactly a MuPAD expression either. You should only use char () of a symbolic expression for display purposes. If you need to generate MATLAB code from a symbolic expression, use matlabFunction (), possibly followed by func2str ()
As an additional warning, this will not use MATLAB syntax (nor pure MuPAD syntax either) and will not work with some variable names, including D, E, I, ...

Because the MATLAB ® parser automatically converts all numbers to double precision, maintain original precision by entering large numbers and high-precision numbers as strings. Instead of str2sym , enter integers using sym and floating-point …

Code: syms f (x,y,z) [Creating symbolic function ‘f’ using syms] f (x,y,z) = 2*x + 5*y - z^2. [Specify the formula for the function created] f (1,2,3) [Pass the arguments to compute the value of the function] This is how our input and output will look like in MATLAB command window:
Feb 26, 2015 · I wrote a symbolic Matlab code which manipulates matrices and vectors for a given problem. The calculations are performed very fast. In order to see the results though I try to print a symbolic expression into a .txt file. Before that I need to convert the sym to a string with char() so then i can fprintf the variable.
