Hi I have a function that determines if 2 lines intersect, are parallel or have infinitely many solutions. I'm able to prompt the user for inputs individually or have them enter the name of the function IPF(slope1,intercept1,slope2,intercept2). If I edit the code I can have it work both ways. However, my professor would like it if the user could decide how they would like to enter the function ( either on one line or being prompted by the function) I have used, if statements, while states, etc, however I have been unable to have a user choose how they want to enter the function without errors.
Here's the current code
function[output]= IPF(m1,b1,m2,b2)
prompt1='Enter your slope value for your first function.\n';
prompt2='Enter your y-intercept value for your first function.\n';
prompt3='Enter your slope value for your second function.\n';
prompt4='Enter your y-intercept value for your second function.\n';
infinite = 'These lines have infinitely many solutions.\n';
parallel = 'These lines have no solutions and are parallel.\n';
intersect = 'These lines intersect.\n';
plot(x,m1*x+b1,x,m2*x+b2)
plot(x,m1*x+b1,x,m2*x+b2)
sol = solve([eqn1, eqn2], [xi, yi]);
fprintf('The lines intersect at %d , %d.\n',xSol,ySol);
plot(x,m1*x+b1,'r',x,m2*x+b2,'b--', xSol,ySol,'*g')
This code displays the results like this:
However, I would like the user to choose between entering the function like above or as shown in the picture below.
I can get each of these to work separately but I'm having no success getting both to work within the same function. I hope that I explained it clearly enough.
I would greatly appreciate any assistance or clarification on this issue.
