if i have 2 cell arrays one containing user names and the other containing coordinate. how can i make the first name equals the first coordinate and so on ? for example i want user1=[xR1 yR1],....,user50=[xR50 yR50],so when i want to use coordinate [xR1 yR1] i call user1.
user = cell(50,50);
name=cell(size(user,2),1);
for i=1:size(user,2)
name{i}=['user ',num2str(i)];
end
users = cell(50, 1);
for i=1:50
users{i} =[xR(i) yR(i)];
end

str = {'user1', 'user2', 'user3'};
cordinates = {[1,2], [2,4], [4,8]};
cellfun(@(x,y) assignin('base', eval('x'), y), str, cordinates)

Hi can I ask for some further description of the cellfun; I get that it allows to pass a function in a cell array;
Can you explain how to interpret @(x,y)
assignin('base', eval('x'), y) -- I get you are assiging the value of y to x but can you explain what 'base' means and why you use the eval('x')??
Thanks a bunch

Cellfun evaluate the function specified by function handle(see the link below) to the contents of cell array.
x and y are input parameters to anonymous functions. See this for detail: anonymous functions. And base here refers to the base workspace, check out documentation.
