I want to have a vector of names, and use a for loop to give a value to each name.

For example, the bcvalues = {'bar01','bar01382,....}

for i = 1:length(bcvalues)

bcvalues(i) = NaN(1,30);

end

However, I obtained a "Conversion to cell from double is not possible."

Any kind of help is appreciated. Thank you.

Matlab also allows "Associative Arrays" (e.g. dictionaries in Python) that can allow key/value pairs to be established.

You can look up containers.Map at:https://www.mathworks.com/help/matlab/matlab_prog/overview-of-the-map-data-structure.html

% Define the keys

S={'bar01','bar01382'}

S = 1×2 cell array

{'bar01'} {'bar01382'}

% Map the keys to values; NaN(1,30) for the first and 2:10 for the second

mapObj = containers.Map(S,{nan(1,30), [2:10]})

mapObj =

Map with properties: Count: 2 KeyType: char ValueType: any

% Examine the values of the object using the keys

mapObj('bar01')

ans = 1×30

NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN

mapObj('bar01382')

ans = 1×9

Yes, if you make the names the fields of a struct,

for i = 1:length(bcvalues)
           S.(bcvalues{i}) = NaN(1,30);
end
