I am getting an error in the following line.In the matlab live editor this was not shown as an error but dont know why in the .m file I am getting this error.
m=1200;
A_f=2;
rho=1.205;
g=9.8;
r=0.3;
f=0.01;
C=0.3;
delta_1 =0.04;
delta_2=0.017;
i_fd=3.29;
i_1=1;
eff_tr=0.95;
delta=1+(delta_1)+(delta_2)*(i_fd)^2*(i_1)^2;
T_whl(1:1436,1)=((delta.*m).*(a(1:1436,1))+0.5.*C.*A_f.*rho.*v(1:1436,1).^2+m.*g.*f).*r; %ERROR :Index in position 1 exceeds array bounds (must not exceed 1).
% a,v in the equation are vectors from .mat file
w(1:1436,1)=v(1:1436,1)./r
global P_load;
P_load(1:1436,1)=T_whl(1:1436,1).*w(1:1436,1);

A = rand(1,10) ;
A(1) % no error
A(2) % no error
A(2,1) % error, becuase A is a row matrix
In your case also check are you trying to teat row matrix as a column matrix? This line:
P_load(1:1436,1)=T_whl(1:1436,1).*w(1:1436,1);
Check it, I don't think index 1 is needed.
P_load(1:1436)=T_whl(1:1436).*w(1:1436);

%I am still getting an error.Please have alookat .mat file attached below
%for the data
eff_tr=0.95;
delta=1+(delta_1)+(delta_2)*(i_fd)^2*(i_1)^2;
T_whl(1:1436)=((delta.*m).*(a(1:1436))+0.5.*C.*A_f.*rho.*v(1:1436).^2+m.*g.*f).*r;%Index exceeds the number of array elements (1).
w(1:1436,1)=v(1:1436,1)./r
global P_load;
P_load(1:1436,1)=T_whl(1:1436,1).*w(1:1436,1);
%Thanks in advance
