MATLAB: Asking User a Question with Variables

changing inputeasyhelpuser inputvariables

Why does this not work? How do I ask the user questions involving changing variables?

Best Answer

solution:

answer=inputdlg({'nodes'});
nodes=str2double(answer(1,1));
nodematrix=Inf(nodes);
A=0;
B=1;
while A<nodes
    B=B+1;
    A=A+1;
    answer=input(['Enter resistance between ',num2str(A),' and ',num2str(B)])
end

See the example:

Get the data from inputdlg;

Say any number 3, 4,5,6 ........

Then

>> str2double(4)
ans =
   NaN
>> str2double(7)
ans =
   NaN

I have removed the str2double in answer statement, str2double convert strings to double precision values, not numeric data

answer=inputdlg({'nodes'});
nodes=str2double(answer(1,1));
nodematrix=nodes6;
A=1;
B=0;
answer=[];
while A < nodes 
    B = B+1;
    while B < nodes
       B = B+1;
       answer =inputdlg(['Enter resistance between ',num2str(A),' and ',num2str(B)]);
       nodematrix(A,B) = str2double(answer)
       nodematrix(B,A) = str2double(answer)
    end 
    A = A+1;
    B = 1; 
end

nodematrix =
     6     5     6     7     8     3
     5     0     6     7     8     2
     6     6     4     7     3     6
     7     7     7     8     5     0
     8     8     3     5     5     6
     3     2     6     0     6     0

MATLAB: Different colors for the title

You need to carefully compose the string. There are syntax error in your statement. Try

A = 1;
B = 1;
p.col=[1 0 0; 0 0 1];
t = title([ ...
    '\color[rgb]{' sprintf('%1.2f,%1.2f,%1.2f', p.col(1,:)) '} A= ' num2str(A), ...
    ',\color[rgb]{' sprintf('%1.2f,%1.2f,%1.2f', p.col(2,:)) '} B= ' num2str(B)], ...
    'fontsize',12, 'Interpreter', 'tex');
