MATLAB: I have to do matrix with ‘single’ vectors

datadoubleMATLABmatrix

Hi everyone,
I done a matrix with 'single' vectors. The problem is that when I do the matrix, matlab changes the values of each vector. For example, the first column represents the years and when I insert the Years vector in the matrix the value changes from 1985 to 0.0198500, this for each column. I'm attacching my code and the matrix below. Is there a way to do a matrix without that matlab changes the values?
Data_table = table(time_date, time2, Hs_buoy, Tm_buoy, Dm_buoy);
HH = single(cell2mat(Data_table.time2(:,:)));
YYMMDD = vertcat(time_date{:});
Years = single(YYMMDD.Year);
Months = single(YYMMDD.Month);
Days = single(YYMMDD.Day);
Hs_tot = cell2mat(Data_table.Hs_buoy(:,:));
Tm_tot = cell2mat(Data_table.Tm_buoy(:,:));
Dm_tot = cell2mat(Data_table.Dm_buoy(:,:));
data_matrix = [Years Months Days HH Hs_tot Tm_tot Dm_tot];
and then the matrix:
data_matrix =

Thank you so much.

Give the command
format long g
The content of the matrix is not changing, only the display of it is. Notice the
1.0e+05 *
which means that the values below that need to be multiplied by 1.0e+05 to understand the values that are stored.
That kind of output with a multiplier at the top is used with format short in order to support a more compact output with limited space.
