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
