Suppose I have a number .. let's say x = 1.4534567809385. If I want to round this off to 5 decimal digits I should get x = 1.45346. However when I try doing this in Matlab using the round function or creating my own function to round it off to 5 decimal digits I am always getting 4 decimal digits. How can I fix this ?

It's just displaying 4 places because you're using format short. Switch to format long and you'll see it correctly.
x = 1.4534567809385;
x5 = round(x, 5)
x5 = 1.4535
format long
x = 1.4534567809385;
x5 = round(x, 5)
x5 =
1.453460000000000
