Hello,

I'm trying to place these numerical values in the steps of a loop and it didn't turn out well, the software doesn't pick it up. Thanks for the helpers

alpha=120; 
theta=90; 
R=40;
S1=20;
S2=15;
r=(R/sqrt(2));
X_e=S1+r*sqrt(2)*sind(alpha)+r*sqrt(2)*sind(alpha+theta);  %Direct kinematics formula in the x axis
Y_e=S2+r*sqrt(2)*cosd(alpha)+r*sqrt(2)*cosd(alpha+theta);  %Direct kinematics formula in the y axis
phi_e=alpha+theta;                                         %Direct kinematics formula in the angle axis
if alpha>160 && theta>110 && R>50 && S1>30 && S2>40
    
   error('One of the entered numbers is not within range, please re-type normal numeric values.')  %Error message
   
else
eqn = sind(alpha)*sind(alpha+theta)+sind(alpha+theta)*sind(alpha+theta)+cosd(alpha)*cosd(alpha+theta)+cosd(alpha+theta)*cosd(alpha+theta);
if eqn==0
    sprintf('In this determinant matrix equation with the %d and %f values there are no singular states.',alpha,theta);
    
else
   sprintf('In this determinant matrix equation with the values %d and %f there are singular states .',alpha,theta);  
    
    
end
end
