Hello, guys, I am trying to have the errors below each other, and they are all in one line. Could you please see the code and give me some suggestions?
if V_breadth_min_check == 0
msg_V_breadth_min = sprintf('Error Loading Parameter V-breadth-min: %f', app.V_breadth_min);
msg = strcat(msg, msg_V_breadth_min, "%s\n%s"); % append the error message to msg
error = error + 1;
elseif V_breadth_min_check == 1
msg_V_breadth_min = sprintf('Loaded Parameter V-breadth-min: %f', app.V_breadth_min);
end
%V_breadth_max_check
if V_breadth_max_check == 0
msg_V_breadth_max = sprintf('Error Loading Parameter V-breadth-max: %f%s\n%s', app.V_breadth_max_check);
msg = strcat(msg, msg_V_breadth_max); % append the error message to msg
error = error + 1;
elseif V_breadth_max_check == 1
msg_V_breadth_max = sprintf('Loaded Parameter V-breadth-max: %f', app.V_breadth_max);
end
error_num = sprintf('# Error: %f%s\n%s', error);
msg = strcat(msg, error_num); % append the error message to msg
% error is used as a flag to see it three is any
% uploaded value vilotated the value range or type condution
if error == 0
msgbox(msg_load, 'Ship Specification Parameters is Loaded');
app.ShipSpecificationButton.BackgroundColor = [0.93,0.69,0.13];
elseif error >= 0
msgbox(msg, 'Error in Ship Specification Parameters', 'error', 'modal');
app.ShipSpecificationButton.BackgroundColor = [1.00,0.00,0.00];
end

Use { } in strcat() and ; (semicolon), to start a new error message from the following line in your msgbox. Here is the corrected code with my some dummy arbitrary input variables:
msg = ' ';
error =0 ;
app.V_breadth_min = 0;
app.V_breadth_max_check = 13;
V_breadth_min_check = [0 1 0 0];
V_breadth_max_check = [1 0 1 0];
for ii=1:4
if V_breadth_min_check(ii) == 0
msg_V_breadth_min = sprintf('Error Loading Parameter V-breadth-min: %f ', app.V_breadth_min);
msg = strcat([msg; {msg_V_breadth_min}]); % append the error message to msg
error = error + 1;
app.V_breadth_min = 0;
end
if V_breadth_max_check(ii) == 0
msg_V_breadth_max = sprintf('Error Loading Parameter V-breadth-max: %f ', app.V_breadth_max_check);
msg = strcat([msg; {msg_V_breadth_max}]); % append the error message to msg
error = error + 1;
app.V_breadth_max = 0;
end
error_num = sprintf('# Error: %d', error);
msg = strcat([msg; {error_num}]); % append the error message to msg
if error == 0
app.ShipSpecificationButton.BackgroundColor = [0.93,0.69,0.13];
elseif error >= 0
msgbox(msg, 'Error in Ship Specification Parameters', 'error', 'modal');
app.ShipSpecificationButton.BackgroundColor = [1.00,0.00,0.00];
end
end

Here is how I would do (see my some arbitrary numerical values for display):
msg_V_breadth_min = sprintf('#2 Error Loading Parameter V-breadth-min: %f \n', pi);
error_num = sprintf('#1 Error: %f \n %s \n %s \n', [pi, date, date]);
msg = error_num; % Dont use strcat!!! to append the error message to msg
msg = strcat([msg, msg_V_breadth_min]);
msgbox(msg, 'Error in Ship Specification Parameters', 'error', 'modal');
