Subscripted assignment dimension mismatch

Hi, this is my code;

[r]=length(matrice_polar);
[www]=29;
matrice_cartesian=zeros(r,www);
temperature=zeros(r,www);
clear www

for i=1:r
    matrice_cartesian(i,2:25)=[matrice_polar(i,1:24)];

      distance_x(i,1)=(x_new-matrice_cartesian(i,2))^2;
      distance_y(i,1)=(y_new-matrice_cartesian(i,3))^2;
      distance_z(i,1)=(z_new-matrice_cartesian(i,4))^2;
      total_distance(i,1)=(distance_x(i,1)+distance_y(i,1)+distance_z(i,1))^(1/2);

      temperature(i,1)=matrice_cartesian(i,10);

end

for i=1:r

      Delta_x(i,1)=(x_new-matrice_cartesian(i,2));
      Delta_y(i,1)=(y_new-matrice_cartesian(i,3));
      Delta_z(i,1)=(z_new-matrice_cartesian(i,4));
      Delta_temperature(i,1)=(temperature-matrice_cartesian(i,10));

end

I get the error "Subscripted assignment dimension mismatch" at the last line:

Delta_temperature(i,1)=(temperature-matrice_cartesian(i,10));

Anyone can help me, why it is happen?

’temperature' is an array, not a scalar, and when the scalar 'matrice_cartesian(i,10)' is subtracted from it, it remains an array. However, you are trying to place it in a single element of 'Delta_temperature' and it doesn’t fit. You need to rethink what it is you are trying to accomplish.

Thank you sir, I think I got the point...
