How do i set the marker and line commands to accept the symbols as inputs

1 visualización (últimos 30 días)
p.LineStyle = input('Select which line style you would like: ','s');
while p.LineStyle ~= ('''-''' | '''--''' | ''':''' | '''-.''' | '''none''')
p.LineStyle = input('Refer to the PDF document for valid inputs: ');
end
I get the error 'Matrix dimensions must agree'

Note that if p is a Mathworks graphics object, then setting p.LineStyle to something invalid would error before getting to the while. That is why I store into a different variable and leave the setting of p.LineStyle until after the input has been validated.

See if the strcmpi (link) function will do what you want.
This works for me:
p.LineStyle = input('Select which line style you would like: ','s');
while ~strcmpi(p.LineStyle, {'''-''' , '''--''' , ''':''' , '''-.''' , '''none'''})
p.LineStyle = input('Refer to the PDF document for valid inputs: ');
end

You need to make it
input('Refer to the PDF document for valid inputs: ','s')
Check input help page for the reason of parameter 's'.

while ~ismember( p.LineStyle ,{'-',':','-.','--','none'})
disp 'Refer to the PDF document for valid inputs:', disp ' ';
p.LineStyle = input('Select which line style you would like: ','s');
end

valid_styles = {'-', '--', ':', '-.', 'none'};
while true
LineStyle = input('Select which line style you would like: ','s');
if ismember(LineStyle, valid_styles)
p.LineStyle = LineStyle;
break;
end
fprintf('valid styles are: %s\n', strjoin(valid_styles, ' '));
end
