Hi

I am trying to change the name of table to Time duration of vehicle speed from Time_duration_vehicle_speed and its two column headings to Interval of speed (rpm) and Duration of speed (s) (all wihtout any underscores). I am not sure how to type the words properly or what the format is to get it be displayed in a normal format with spaces.

Any help would be appreciated, Thankyou.

This should work in R2020b —

Interval_of_speed_rpm = randn(5,1);
Duration_of_speed_sec = randn(5,1);
Time_duration_vehicle_speed = table(Interval_of_speed_rpm, Duration_of_speed_sec)
Time_duration_vehicle_speed = 5×2 table
    Interval_of_speed_rpm    Duration_of_speed_sec
    _____________________    _____________________

           -1.1854                    0.7449      
           -1.2668                 -0.072663      
           0.41819                  -0.28403      
            -1.182                    -2.618      
          -0.82624                  -0.38265      
VN = Time_duration_vehicle_speed.Properties.VariableNames
VN = 1×2 cell array
    {'Interval_of_speed_rpm'}    {'Duration_of_speed_sec'}
Time_duration_vehicle_speed.Properties.VariableNames = cellfun(@(x)strrep(x, '_', ' '), VN, 'Unif',0)
Time_duration_vehicle_speed = 5×2 table
    Interval of speed rpm    Duration of speed sec
    _____________________    _____________________

           -1.1854                    0.7449      
           -1.2668                 -0.072663      
           0.41819                  -0.28403      
            -1.182                    -2.618      
          -0.82624                  -0.38265      

EDIT — (9 Aug 2023 at 11:11)

There cannot be any spaces in the name of the table.

The name of the table has to be a valid MATLAB variable name ("Time_duration_vehicle_speed" is OK; "Time duration vehicle speed" is not), but the name of the variables in the table can be specified when you create the table. Here's one way to do that:

Interval_Of_Speed_rpm = rand(8,1);
Duration_Of_Speed_s = rand(8,1);
% Time_duration_vehicle_speed = table(Interval_Of_Speed_rpm,Duration_Of_Speed_s)
Time_duration_vehicle_speed = table(Interval_Of_Speed_rpm,Duration_Of_Speed_s, ...
    'VariableNames',{'Interval (RPM)','Duration (s)'})
Time_duration_vehicle_speed = 8×2 table
    Interval (RPM)    Duration (s)
