code:

fprintf(fid1,'%s%0.8E\r\n',' ',Frequence(1),)

Is there any way to do this?

One approach —

expstr = @(x) [x(:).*10.^ceil(-log10(abs(x(:)+(x==0)))) floor(log10(abs(x(:)+(x==0))))];       % Updated: 2021 05 04

fid1 = 1;
Frequence(:,1) = 8.90000000E+007;
fprintf(fid1,'%.8fe%+04d', expstr(Frequence(:,1)))

8.90000000e+007

As requested.
