Index exceeds matrix dimensions.
Error in uisignalbuilder_speed/Import_Excel (line 595)
       timefromworkspace = evalin('base','speedfromworkspace(:,1);');%test

function Import_Excel()
        a=uigetfile('*xls');
        name1=cellstr(a);
        [~,a] =xlsread(name1{1});% read data from excel file%test replaced 1
        
        
            % removeallsignals();%TEST
       evalin('base', 'clear speedfromworkspace;');
        assignin('base','speedfromworkspace',a);
       removeallsignals();
  
       timefromworkspace = evalin('base','speedfromworkspace(:,1);'); // GETTING ERROR 

HERE

       speedfromworkspace = evalin('base','speedfromworkspace(:,2);');

Best option is to debug, examine the workspace, etc, although all the evalin and assignin operations make it more difficult than it should be to debug code.

Best option is to rewrite your code to not mess around in other workspaces.
