Hello, I have an array of trial names (i.e. trials = {'Standing', 'Walking'}, etc.) and I want to loop through the array to create new variables like so:

for trialnum = 1:11;

trial = trials(trialnum)

acc_(trial) = data.sub.(trial).acceleration

end

Hi,

You can use the code below

trials = {'Standing','Walking'} 
for trialnum = 1:length(trials) 
    trial = trials{trialnum} 
    eval(['acc_' trial '= data.sub.(trial).acceleration']) 
end 

But it is not recommended to name variables dynamically

"But it is not recommended to name variables dynamically "

Then perhaps the OP might appreciate some examples of simpler, more efficeint, more reliable code?
