mean_speed_R, mean_speed_T and mean_speed_N are the components of mean_U0_vector. How should I express the unit vectors along R, T and N? Thanks a lot
I am writing the code as follows
mean_speed_R = mean(speed_R); %u_R_0
mean_speed_T = mean(speed_T); %u_T_0
mean_speed_N = mean(speed_N); %u_N_0
mean_U0_vector = mean_speed_R + mean_speed_T +mean_speed_N; % u_0 vector
magnitude_U0_mean_RTN = sqrt((mean_speed_R)^2 + (mean_speed_T)^2 + (mean_speed_N)^2);

Put the components in a vector:
mean_U0_vector = [mean_speed_R, mean_speed_T, mean_speed_N]; % u_0 vector
Then the unit vectors are [1 0 0], [0 1 0], and [0 0 1].
By the way, with mean_U0_vector being a vector, you can simplify the expression for magnitude_U0_mean_RTN:
magnitude_U0_mean_RTN = sqrt(sum(mean_U0_vector.^2,2));

Thank you so much :).
Is it possible to copy equations written in Matlab to latex directly? Thanks again.
