Im trying to make dynamic variables, based on the names of colums of the tables of some data sets.
This is my Code, the bolded section is my issue
varnammes = ["SpeedGoatT" "imu1_accel_x" "imu1_accel_y" "imu1_accel_z" "imu1_gyro_x" "imu1_gyro_y" "imu1_gyro_z" "imu1_orient_i" "imu1_orient_j" "imu1_orient_k" "imu1_orient_r" "imu2_accel_x" "imu2_accel_y" "imu2_accel_z" "imu2_gyro_x" "imu2_gyro_y" "imu2_gyro_z" "imu2_orient_i" "imu2_orient_j" "imu2_orient_k" "imu2_orient_r" "imu3_accel_x" "imu3_accel_y" "imu3_accel_z" "imu3_gyro_x" "imu3_gyro_y" "imu3_gyro_z" "imu3_orient_i" "imu3_orient_j" "imu3_orient_k" "imu3_orient_r" "imu4_accel_x" "imu4_accel_y" "imu4_accel_z" "imu4_gyro_x" "imu4_gyro_y" "imu4_gyro_z" "imu4_orient_i" "imu4_orient_j" "imu4_orient_k" "imu4_orient_r" "imu5_accel_x" "imu5_accel_y" "imu5_accel_z" "imu5_gyro_x" "imu5_gyro_y" "imu5_gyro_z" "imu5_orient_i" "imu5_orient_j" "imu5_orient_k" "imu5_orient_r" "imu6_accel_x" "imu6_accel_y" "imu6_accel_z" "imu6_gyro_x" "imu6_gyro_y" "imu6_gyro_z" "imu6_orient_i" "imu6_orient_j" "imu6_orient_k" "imu6_orient_r" "imu7_accel_x" "imu7_accel_y" "imu7_accel_z" "imu7_gyro_x" "imu7_gyro_y" "imu7_gyro_z" "imu7_orient_i" "imu7_orient_j" "imu7_orient_k" "imu7_orient_r"];
Tables = struct();
for i = 1:length(files)
load(files(i))
varName = sprintf(‘Table0%d’, i-1); % Create a variable name
Tables.(varName) = logsout.FileLogSignals{4}.Values;% Set the variable in the structure
Tables.(varName) = timeseries2timetable(Tables.(varName));
Tables.(varName) = timetable2table(Tables.(varName));
Tables.(varName) = splitvars(Tables.(varName), 2);
Tables.(varName).Properties.VariableNames(2:end) = varnammes;
for x = 1:length(varnammes)
varName = [char(varnammes(x)) num2str(i-1)];
eval([varName ‘ = x^2;’]);
end
end

This is a test version that is makeing the variables I want but instead of makeing them x^2 i want them to be the column that goes with the variable.
The normal code would be something like
imu1_accel_x = Tables.Table00{:,3};
or
imu1_accel_x = Tables.Table00.imu1_accel_x;
makeing the output being imu1_accel_x0 , with all the values of column imu1_accel_x
I tried makeing the eval line:
eval([varName ‘ = Tables.Table00.imu1_accel_x;’]);
but i got an error and dont know why or how to make it work as inteded
Ive sent an image of the output given the X^2 which works as intended.
