Insert Mathlab figure in Latex

Hi,

I have been unable to insert Matlab figure in my LaTex document and I am not sure what the problem is.

I usually use the code below to create the document in MATLAB.

  print -depsc Nocostfunction41.eps

\begin {figure}[H]

\centering

\includegraphics[scale =0.4]{Simulation Figures/Nocostfunction41}\\

\caption{Figure 1}

\label{figure1}

\end{figure}

I have attached a screenshot of the error. I am using BigSur OS and TexShop, MATLAB R2021

Has anyone experience this type of problem

Hello Telema,

It appears that the Latex compiler you are using could not find the file. Usually empty spaces give errors. Try renaming the folder and let's see.

By the way, I wrote a simple script for a colleague a few weeks ago to print custom graphics, save them, etc. It might be helpful.

I have changed the default save format to eps to match your case.

Best,

Alberto.

function myplot(x, y, varargin)
    % Function that plot two given datasets x, y with same dimensions
    % Examples:
    %   myplot(x, y)
    %   myplot(x, y, 'xlabel', '$\phi$')
    %   myplot(x, y, 'xlabel', '$\phi$', 'grid', 'on')

    customfolderpath = [];
    % Constants

    colorbw = brewermap(Ncolors, 'Spectral');

    % Check varargin inputs (Write custom definitions in case you want to
    % have a more generalized routine)
    % The input will be, e.g., myplot(x, y, 'xlabelname', xlabelname)
    if nargin - 2 > 0
        for i = 1:2:nargin-2
            switch lower(varargin{i})
                case {'xlabelname', 'xlabel'}
                    xlabelname = varargin{i + 1};
                case {'ylabelname', 'ylabel'}
                    ylabelname = varargin{i + 1};
                case {'filename', 'customfilename'}
                    customfilename = varargin{i + 1};
                case 'grid'
                    config.grid = varargin{i + 1};
                case 'saveformat'
                    config.saveformat = varargin{i + 1};
                % Custom stuff ...    
            end
        end
    end
    % Set up figure
    [fig, axes] = generate_figure(config);
    xlabel(axes, xlabelname, 'FontSize', config.fontsize, 'interpreter', 'latex');
    ylabel(axes, ylabelname, 'FontSize', config.fontsize, 'interpreter', 'latex');
    % Plot
    for i=1:Ncolors
        plot(x(i, :), y(i, :), 'color', colorbw(i, :), 'LineWidth', config.linewidth);
    end
    % Save figure
    folderpath = strcat(pwd, customfolderpath, '\');
    filename = customfilename;
    saveas(fig, strcat(folderpath, filename), 'epsc');
end

% SUB-PASS FUNCTIONS
function [fig, axes] = generate_figure(config)
    % Function to generate a predefined figure
    fig = figure;

    grid(axes, config.grid); box(axes, config.box); hold(axes, config.hold); axes.Layer = config.layer;
end

function config = default_config
    % Set default configuration parameters

Thank you so much.

Removing the space in the folder solved the problem.
