I know it's a common question here about supressing output, but I can't seem to find a missing semi-colon in my code, but yet I have a matrix displayed everytime.

The issue seems to be with the last two functions, namely table2array and readtable. This would be a minor issue if I had to import a small database, but I have hundreds of files and clc-ing everytime is just not efficient if I want to trace-back my progress.

I've attached a txt file that you can use to test the function with.

If it turns out to be a missing semi-colon, I will humbly apologize with a MATLAB Haiku 俳句。

Edit: When calling the function, I add a semi-colon.

Edit: The Issue was a semi-colon. As promised, here is my Haiku:

I was not a fool

Until semi-colon came,

Now I am a fool

function EEM = importData(filename)
%IMPORTFILE Import data from a text file
%  EEM = IMPORTFILE(FILENAME) reads data from text file FILENAME for the
%  default selection.  Returns the numeric data.
%
%  EEM = IMPORTFILE(FILE, DATALINES) reads data for the specified row
%  interval(s) of text file FILENAME. Specify DATALINES as a positive
%  scalar integer or a N-by-2 array of positive scalar integers for
%  dis-contiguous row intervals.
%
%  Example:
%  EEM = importfile("C:\Users\user\Documents\Flurine\FL_DATASET\ind944h-3
% .txt", [18, Inf]);
%
%  See also READTABLE.

%% Input handling
% If dataLines is not specified, define defaults
    if nargin < 2
        dataLines = [18, Inf];
    end
    
    %% Set up the Import Options and import the data
    opts = delimitedTextImportOptions("NumVariables", 102);
    
    % Specify range and delimiter
    opts.DataLines = dataLines;
    opts.Delimiter = "\t";
    
    % Specify column names and types
    opts = setvartype(opts,"double"); 
    
    % Specify file level properties
    opts.ExtraColumnsRule = "ignore";
    opts.EmptyLineRule = "read";
    
    % Import the data
    EEM = readtable(filename, opts);
    
    %% Convert to output type
    EEM = table2array(EEM);
end

I do not see any missing semicolons in the file, so the most likely problem is that there is one missing when you call the function (added here):

EEM = importData(filename);

Without your code, I cannot be certain that is the problem.

Thank you!

Nothing foolish at all! You were simply so used to looking at your code that you didn’t see that line for what it was. Not having that familiarity with it, I found it. (This is the reason newspaper and other publishers hire proofreaders and copy editors.)

Here is the function that calls the function

function [database] = assembler(DIRECTORIES)
    if(isa(DIRECTORIES,'struct'))
        database = DIRECTORIES;
        return
    end
    dictionary = load('dictionary.mat');
    k=1;
    for i=1:DIRECTORIES.length
        cd(DIRECTORIES(i));
        dinfo = dir('*.txt');
        for j=1:length(dinfo)
            fileName = dinfo(j).name;
    
            abbreviation = fileName(1:3);
            concentration = fileName(4:6);
            unitPrefix = fileName(7);
    
            % Name
            index = find(dictionary.substanceNameabbreviation == abbreviation);
            sunbstanceName = dictionary.substanceName(index);
    
            % Concentration
            index = find(dictionary.unitPrefix == unitPrefix);
            unit = dictionary.unit(index);
            concentration =  str2num(concentration) * unit;
    
            % Import ASCII Data
            Matrix = importData(fileName);
            
            
            % Extract EEM, Excitation and Emission Spectrum
            emissionSpectrum = Matrix(2:end,1);
            excitationSpectrum = Matrix(1,2:end);
            EEM = Matrix(2:end,2:end)
    
            database(k).sunbstanceName = sunbstanceName;
            database(k).abbreviation = abbreviation;
            database(k).concentration = concentration;
            database(k).emissionSpectrum = emissionSpectrum;
            database(k).excitationSpectrum = excitationSpectrum;
            database(k).EEM = EEM;
            database(k).path = DIRECTORIES(i);
            database(k).fileName = fileName;
    
            k = k+1;
        end
    end
    %clc
end

Flurine.zip

I was hoping this would be a simpler problem. Thank you for taking the time.

I've included the zip file with all functions and datasets you could use to conduct your test. Since I started with it today, it's a bit baron of comments (really, sorry).

The main file is "Flurine" and all you have to do is run it. It will prompt a uigetdir, at which point you should select the database folder that I provided you in the zip. Afterwards you'll notice that upon importing, in the livetex file you'll have all 30-ish matrices displayed in sequence.
