Please see our. Skip to content. Since you know the row size of the matrix you are working with, one option for the condition in the while statement would be to continue iterating so long as the calculated value of ‘r’ for the next iteration is less than or equal to the row size of the matrix. T_WATERback=ones(1,n_windings)*T_water_hp; T_WIREback=ones(1,n_windings)*(180+273.15); cond_1 = sum(abs(T_WATERfront-T_WATERback)>eps) == length(T_WATERfront). You may note here that as the value of N is decreasing in each iteration, it will always satisfy the condition and hence will continue working infinitely.
