How to display the filename correctly?

I am trying to export a figure with a file name that is derived from the string name after a section of a code. Below is the export fig part. But for some reason, instead of printing the actual name of string the code prints fig_name as the file name. What can be done to avoid this?

    p1 = strfind(fname,'.csv');
    fig_name = string(fname(1:1:p1-1));
    fig_name = sprintf(fig_name + '.png')
    
    %% export the figure
    export_fig fig_name -transparent

You are using the command format of export_fig. MATLAB does not understand fig_name is used to refer a variable and just consider it as a string. Use the functional format

export_fig(fig_name, '-transparent')
