Dear all, I have vector with numbers and fraction. How can I reduce fraction number.?for example a=[1.23456789 6.14521456 7.906342678 10.47609352]
expect results should be: re=[ 1.2 6.1 7.9 10.4] Thanks...

One way to display a decimal number to one decimal place:
sprintf('%5.1f',a)
Note that this will not change the value stored in a; it will only display it differently.

If you want to store a value that is changed, use the round function:
re = round(a,1)
Or you might want fix instead.
