I have a number like this:
2.32166873546944
I want to take only four numbers after the decimal point and without rounding, that is, I only want:
2.3216
How do I do this in Matlab ?

You want to truncate after the 4th decimal place? Easy peasy.
You shift where the decimal place lies, then use floor.
format long g
x = 2.32166873546944
y = floor(x*10000)/10000

If you want "four digits after the decimal place" you should probably use fix() instead of floor()
format long g
x = 2.32166873546944
xn = -x
y1 = floor(x*10000)/10000
y2 = fix(x*100000)/100000
y3 = floor(xn*10000)/10000
y4 = fix(xn*10000)/10000
