what is an alternative to syms x function in matlab

In MATLAB, the syms function is used to define symbolic variables. If you are looking for an alternative to the syms function, you can use the sym function instead.

Here is an example:

main.m
x = sym('x');
14 chars
2 lines

In this example, sym('x') creates a symbolic variable named x.

You can also create multiple symbolic variables at once by passing a string or a cell array of strings to the sym function. For example:

main.m
[sym('x'), sym('y'), sym('z')]
31 chars
2 lines

This will create three symbolic variables named x, y, and z.

Using the sym function should provide an alternative to using the syms function in MATLAB.
