Execute multiple functions in parfor

Hi, Currently I have several functions, named function1.m, function2.m, function3.m , ..., function10.m. Each function is independent each other. I would like to run the all the functions in one execution

currently, my code is like this, it runs the functions one by one.

for i = 1 : 10
result = eval(sprintf('function%d.m',i));
end

I would like to know is there a way to rewrite the code in parfor instead of for, as I know that eval does not work in parfor. Thank you

functions = {@function1, @function2, @function3, @function4, @function5, @function6, @function7, @function8, @function9, @function10};

parfor i = 1 : length(functions)
  functions{i}()
end

Your current code is going to be a problem, as it will attempt to access the field named "m" in the return value of function "function1"

Any time you use eval(), you are probably doing something wrong. (There are a few times that it is needed, but not often.)

Thank you for the solution, but is there a quick way to create the functions array rather than explicitly list @function1 up to @function10?

[Walter Roberson]

functions = cell(10,1);

for i = 1 : 10

functions{i} = str2func(sprintf('function%d',i));

end

parfor i = 1 : length(functions)

functions{i}()

end

Thanks a lot :)
