I was assigned to work on the aesthetics of a table that shows collected data as string.
I want to show the numbers with 4 digits percision, but whenever the number is bigger the 10e-5, the output will include all the zeros, and only the four digits, e.g:
x=0.000123456;
y=0.0000123456;
solx=num2str(x,'%.4G');
soly=num2str(y,'%.4G');
solx
soly
Is there any way that I can get solx to be formatted like soly?

soly=num2str(y,'%.3E')
solx=num2str(x,'%.3E')

Write a function which can change the display format based on the magnitude of the data.

Simon is correct.
The only conditional formatting that MATLAB supplies in any released version, is what is done automatically by "format short" or "format long", or done by a %g format for sprintf() or fprintf() or compose() -- none of which permit tuning the boundaries of when values are to be shown in which varient.
