I'm running a script that finds the derivative using the centered difference, but when putting all the results in a table (using fprintf) its all perfect except for the first 4 values of h (they're decimal when the rest is in scientific notation)
how do i put 0.1 , 0.01 , 0.001 and 0,0001 in scientific notation? (1e-1, 1e-2,1e-3,1e-4) ?

heres what i have (red rectangle is what i want to change)



thx brahs

Force it to print the way you want, but keep what you have so the calculations are done correctly?

i.e.

fprintf('blahblah, '1e-' & i, derf, err)

something like that

I don't remember exact matlab syntax, sorry.
