I know this might be dumb but it is messing me up so much. I have a table with data that is in scientific notation. I would like for all the numbers to be displayed to the same power of 10^-10. for example instead of 1.5e-9 , I would like it to be displayed as 15e-10.
MATLAB Script
----------------------------------------------------------------------------------------------------
clear; clc;
x=[702.8530e-012; 1.1511e-009; 1.0467e-009; 1.3369e-009; 723.8877e-012; 748.1630e-012; 1.0198e-009; 1.1897e-009]
number=[ 1; 2; 3; 4; 5; 6; 7; 8]
T=table(number,x)
------------------------------------------------------------------------------------------------------
I would like for all those e-9 to be e-10, does not matter if some numbers have more digits or significant figures than others, the only thing that I am looking for is that 10^-10 format.
if anyone can help, I appreciate it a lot!

table() objects do not support that customization. You would need to switch the items to text

Oh I see, what would be a possible way then? Maybe if it was a 8x2 matrix instead of a table? If possible, how can that customization should be done?

Ran in:
x=[702.8530e-012; 1.1511e-009; 1.0467e-009; 1.3369e-009; 723.8877e-012; 748.1630e-012; 1.0198e-009; 1.1897e-009]
x = 8×1
1.0e+-8 * 0.0703 0.1151 0.1047 0.1337 0.0724 0.0748 0.1020 0.1190
number=[ 1; 2; 3; 4; 5; 6; 7; 8]
number = 8×1
1 2 3 4 5 6 7 8
T=table(number,x)
T = 8×2 table
number x ______ __________ 1 7.0285e-10 2 1.1511e-09 3 1.0467e-09 4 1.3369e-09 5 7.2389e-10 6 7.4816e-10 7 1.0198e-09 8 1.1897e-09
T.x = compose("%8.4f", T.x/1e-10) + "E-10"
T = 8×2 table
number x ______ ______________ 1 " 7.0285E-10" 2 " 11.5110E-10" 3 " 10.4670E-10" 4 " 13.3690E-10" 5 " 7.2389E-10" 6 " 7.4816E-10" 7 " 10.1980E-10" 8 " 11.8970E-10"
The "8" part of the %8.4f might need to be adjusted if you had values that were higher scale relative to 1e-10 . Also note that values smaller than 1e-16 will show up as 0
