why am i getting syntax error for linspace in If statement?

 if (Z(1,1)==z && Z(2,1)== z && Z(3,1)==z)
         { 
             t = linspace(0,1);                          % case 1 = when triangle is parallel to cutting plane
             x = X(1,1)+t*(X(2,1)-X(1,1));
             y =Y(1,1)+t*(Y(2,1)-Y(1,1));
             z = Z(1,1)+t*(Z(2,1)-Z(1,1));
             plot3(x,y,z);
             hold on;
             x = X(2,1)+t*(X(3,1)-X(2,1));
             y = Y(2,1)+t*(Y(3,1)-Y(2,1));
             z = Z(2,1)+t*(Z(3,1)-Z(2,1));
             plot3(x,y,z);
             hold on;
             x = X(1,1)+t*(X(3,1)-X(1,1));
             y = Y(1,1)+t*(Y(3,1)-Y(1,1));
             z = Z(1,1)+t*(Z(3,1)-Z(1,1));
             plot3(x,y,z);
             hold on;
          }
