MATLAB: Can I use for loop to do the same process to four tables

for looptable

Hiya, Im trying to execute this for loop, but as well as changing the index, I also want to chnage the table that the original for loop is acting on.
I have four tables each with a different club name-
FMData_Test_BBSH_reordered
FMData_Test_NewCal_reordered
FMData_Test_3Wood_reordered
FMData_Test_Wooden_reordered
My original loop below works,
for i=1:13
%Use rotation matrix to rotate the offline (x) and Carry distance (y)

BBSH_x(i)=(FMData_Test_BBSH_reordered{i,3}.*cos(Theta_carry(1,1)))-(FMData_Test_BBSH_reordered{i,4}*sin(Theta_carry(1,1)));
BBSH_y(i)=(FMData_Test_BBSH_reordered{i,3}.*sin(Theta_carry(1,1)))+(FMData_Test_BBSH_reordered{i,4}*cos(Theta_carry(1,1)));
end
but rather than write this code out four times, each time changing the club name e.g.BBSH to the next club I was wondeirng if i could create another for loop to do this.
I have tried :
Club_names={'BBSH','New Cal','Ping 3 Wood','Wooden'};
for ii=Club_names
for i=1:13
%Use rotation matrix to rotate the offline (x) and Carry distance (y)
ii_x(i)=(FMData_Test_ii_reordered{i,3}.*cos(Theta_carry(1,1)))-(FMData_Test_ii_reordered{i,4}*sin(Theta_carry(1,1)));
ii_y(i)=(FMData_Test_ii_reordered{i,3}.*sin(Theta_carry(1,1)))+(FMData_Test_ii_reordered{i,4}*cos(Theta_carry(1,1)));
end
end
but this doesnt work as Matlab says the varibale FMData_Test_ii_reordered is not defined.
Any suggestions greatly appreciated.

  • To the best of my knowledge it is not possible to dynamically loop through variables. I would suggest combining the tables into one variable, perhaps a structure, and then looping through the index of that new variable.
    structure = struct('table',{FMData_Test_BBSH_reordered, FMData_Test_NewCal_reordered, FMData_Test_3Wood_reordered, FMData_Test_Wooden_reordered});
    for i = 1:length(structure)
    % Do you stuff here. Call each table with structure(i).table
    end
