When I run:
num2str(5.7831e-04)
I get: '0.00057831'
How can I obtain '5.7831e-04' instead?

Use sprintf()
sprintf('%.4e', 5.7831e-04)

Storing a number is not a matter of format. Inside memory, it will be saved as a double datatype with same bits. The format is only important if you want to print the number.
