how to know the constant value in matlab in matlab

In MATLAB, you can use the built-in "eps" function to determine the value of the machine epsilon, which represents the spacing between floating-point numbers.

Here's how you can use it:

main.m
eps_value = eps;
disp(eps_value);
34 chars
3 lines

The variable "eps_value" will store the value of the machine epsilon, and then it will be displayed using the "disp" function.

Another important constant in MATLAB is "pi", which represents the mathematical constant pi. You can use it directly in your calculations or assign it to a variable if needed.

main.m
pi_value = pi;
disp(pi_value);
31 chars
3 lines

The variable "pi_value" will store the value of pi and then display it using the "disp" function.
