Finding a string exact match

I have a list of parameters

parameters = {'Freq','I','U','P','Q','S','PF'};

and a list of names

names = {'Freq_min', 'Freq_max, 'Freq_avg','I_min', 'I_max,I_avg'....} and so on. Every parameter has many values like min, max, avg, peak, etc. There are 140 names in the array.

names is a cell array that contains the variable names from table T.

I need to find every position in the array names that has the string 'Freq' and then pull all data rows in that column, so this is the code i'm using:

for n = 1:length(parameters)    
    x = parameters(~ismember(parameters,parameters{n}));  
    s.(strcat(parametros{n},'_','Min')) = ...
        T(:,contains(names,parameters{n})&contains(nombres,'Min')&strncmpi(parameters(n),names,2));
    s.(strcat(parametros{n},'_','Avg')) = ...
        T(:,contains(nombres,parameters{n})&contains(names,'Avg')&strncmpi(parameters(n),names,2));
    s.(strcat(parametros{n},'_','Max')) = ...
        T(:,contains(nombres,parameters{n})&contains(names,'Max')&strncmpi(parameters(n),names,2));      
end

And it works well, until it hits 'PF' because it also finds 'P' and i cannot find the way for Matlab to discriminate for 'P' not being containd in 'PF'

Or maybe I'm just over complicating the solution and there's an easier way.

Thanks.

I have no idea what you were trying to do with:

 x = parameters(~ismember(parameters,parameters{n}));  

which is obtained more simply (and a lot more understandably) with:

 x = parameters([1:n-1, n+1:end]); 

as long as there's no duplicate entry in parameters

If I understand correctly what you're trying to achieve:

paramlocs = cellfun(@(p) find(StartsWith(names, p)), strcat(parameters, '_'), 'UniformOutput', false)

which will give you a cell array paramlocs where paramlocs{i} is the index of the elements of names which starts with [paramaters{i}, '_']
