MATLAB: I keep getting a syntax error with the program??

elseif statementif statementsyntax error

I'm creating a program that identifies x and y coordinates in a Cartesian coordinate system.
x=input('Enter value for x: '); y=input('Enter value for y: '); if x=0 & y=0 disp('This point is located at the origin.') elseif x>0 & y=0 fprintf disp('This point is located on the x-axis.') elseif x=0 & y>0 disp('This point is located on the y-axis.') elseif x>0 & y>0 disp('This point is located in the first quadrant.') elseif x<0 & y>0 disp('This point is located in the second quadrant.') elseif x<0 & y<0 disp('This point is located in the third quadrant.') elseif x>0 & y<0 disp('This point is located in the fourth quadrant.') end
I keep getting a syntax error with the x=0? The error tells me that '=' might be invalid Matlab syntax.
What am I doing wrong?

Best Answer

in the If statement you need to use '==' Your first if statement would be
if x==0 & y==0 
 disp('This point is located at the origin.')
Your entire code
x=input('Enter value for x: '); 
y=input('Enter value for y: '); 
if x==0 & y==0 
    disp('This point is located at the origin.')
elseif x>0 & y==0 
    disp('This point is located on the x-axis.') 
elseif x==0 & y>0 
    disp('This point is located on the y-axis.') 
elseif x>0 & y>0 
    disp('This point is located in the first quadrant.') 
elseif x<0 & y>0 
    disp('This point is located in the second quadrant.') 
elseif x<0 & y<0 
    disp('This point is located in the third quadrant.') 
elseif x>0 & y<0 
    disp('This point is located in the fourth quadrant.') 
end
