how to take just the 4 digits after point value (from vec1) and change the remaining to zero (as shown in vec2)
vec1 = [0.58350447046727 0.33968780507470 0.95356905156671]
vec2 = [0.58350000000000 0.33970000000000 0.95360000000000]

round down to 4 decimals:
vec2 = round(vec1, 4);
display with remaining zeros:
format long
vec2
I personally greatly dislike that display format and much prefer format longg.
