Hi,
To create a symbolic vector with a specific number of variables in MATLAB, you can use the “syms” function along with either a loop or the “sym” function.
You can start by generating variable names in the form of x1, x2, ..., xn using MATLAB's “arrayfun” function. Pass these names to the “syms” function to define them as symbolic variables. The “sym” function is used to compile these variables into a symbolic vector.
Please refer to the following example code demonstrating the process described above:
function sym_vector = createSymbolicVector(n)
% Generate variable names dynamically
varNames = arrayfun(@(i) ['x', num2str(i)], 1:n, 'UniformOutput', false);
% Define these as symbolic variables
syms(varNames{:});
% Construct a symbolic vector from these variables
sym_vector = sym(varNames);
end
You may refer to the following MathWorks documentation to know more about the functions mentioned above:
- sym: https://www.mathworks.com/help/symbolic/sym.html
- arrayfun: https://www.mathworks.com/help/matlab/ref/arrayfun.html
I hope the solution provided above is helpful.
