Is it possible to show numbers in non-engineering format in MATLAB?

I noticed when applying my normalization method below:

%# get max and min of spreadsheet(494021x42)
maxM = max(M(:)) %# Max = 693375640
minM = min(M(:)) %# Min = 0 

%# normalize to -1...1
Mnormalize = ((M-minM)./(maxM-minM) - 0.5 ) *2;

That when I try to de-normalize with the below method:

%# to "de-normalize", apply the calculations in reverse
vec = (Mnormalize./2+0.5) * (maxM-minM) + minM

I dont quite get the correct answers back, below is the original spreadsheet snippet picture:

and here is the de-normalized snippet:

Notice how its almost the exact same except for column six, for some reason the output is placing the decimal in the wrong place.

So my questions is:

1) How do I fix column 6

and an extra question is:

2) how do I remove trailing zeros

Answer 1

To remove the trailing zeros, use ROUND.
