MATLAB: Comparing and locating string values

indexlocationstring

I have a x=1×10 string of colors and the user enters a a=1×3 string of colors. Im trying to get the index of the location in the x-variable. How can i achieve that?

% my code

x=["Brown","Blue","Red","Orange","Purple","Black","Yellow","White"];

% User input

a=["Brown","Red"];

% I try this but it does not work

idx=strcmpi(a(1:2),x);

Best Answer

Please try following command.

ret = find(ismember(x,a))

ismember

find

MATLAB: How to write a script file that asks the user to input the total resistance for a resistor and then outputs a list of colors for the bands in order (1, 2, 3)

This takes me back to my amateur radio days (although I was used to mapping from stripes to resistance):

Colours = {'black' 'brown' 'red' 'orange' 'yellow' 'green' 'blue' 'violet' 'gray' 'white'};
Values = [0:9];
Rc = inputdlg('Stripe your resistor!  What is its resistance (Ω)? ')
Rstr = Rc{:};
for k1 = 1:length(Rstr)
    parse{k1} = Rstr(k1);
end
Mult = fix(log10(str2num(Rstr)));
Bands = parse(1:2);
Resistor = Colours([str2num(Bands{1})+1, str2num(Bands{2})+1, Mult])
fprintf(1, '\tYour resistor of %s Ohms will be striped %s, %s, %s\n\n', Rstr, char(Resistor{1}), char(Resistor{2}), char(Resistor{3}))

Example output:

Your resistor of 47000 Ohms will be striped yellow, violet, orange
