Take a look at the filloutliers and rmoutliers functions on this documentation page.

MATLAB: How to make array from characters from variables

Create a cell array out of the character array:

c = cellstr(val);

Then, each cell element is a string that can be used:

c{1}

for example, is the first string. (Notice the use of curly brackets there.) You can read more about the use of cell array in the documentation.

MATLAB: Read date from character string

This is easy using regexp to match the date substring:

C = {'GOME_O3-NO2-NO2Tropo-BrO-SO2-H2O-HCHO_L2_20151031233116_051_METOPB_16186_DLR_03.HDF5'
  'GOME_O3-NO2-NO2Tropo-BrO-SO2-H2O-HCHO_L2_20151101001652_051_METOPA_46873_DLR_03.HDF5'
  'GOME_O3-NO2-NO2Tropo-BrO-SO2-H2O-HCHO_L2_20151101011234_051_METOPB_16187_DLR_03.HDF5'
  'GOME_O3-NO2-NO2Tropo-BrO-SO2-H2O-HCHO_L2_20151101015816_050_METOPA_46874_DLR_03.HDF5'
  'GOME_O3-NO2-NO2Tropo-BrO-SO2-H2O-HCHO_L2_20151101025358_051_METOPB_16188_DLR_03.HDF5'
  'GOME_O3-NO2-NO2Tropo-BrO-SO2-H2O-HCHO_L2_20151101033940_050_METOPA_46875_DLR_03.HDF5'
  'GOME_O3-NO2-NO2Tropo-BrO-H2O-HCHO_L2_20070920104919_049_METOPA_04770_DLR_03.HDF5'};
D = regexp(C,'\d{14}','match','once');
E = datenum(D,'yyyymmddHHMMSS');

and the output:

>> datevec(E)
ans =
 2015     10     31     23     31     16
 2015     11      1      0     16     52
 2015     11      1      1     12     34
 2015     11      1      1     58     16
 2015     11      1      2     53     58
 2015     11      1      3     39     40
 2007      9     20     10     49     19
