Is there a quick way to dumping a collection of variables to a structure, using the variable names as the structure fields? The "load" function basically does this somehow? Sorry if this has been answered, I'm just finding a solution quickly.

i.e.

clear
a = 'adsf'
b = rand(10);

x = var2struct(a,b)

x.a
x.b

Also, what about the reverse? Dumping a.* variables to the current scope?
clear
x.a='asdf'
x.b=rand(10);
dumpstruct(x)
a
b

.... and I don't think

can do this, unless I don't understand all the features of that function.

See this FEX tool:

It's unlikely that you'd benefit from a tool like this. You'll expend just as many keystrokes by typing

x.a='adsf'
x.b=rand(10);

Although, here's a possible implementation:

function x=var2struct(varargin)


for ii=1:length(varargin)

x.(inputname(varargin{ii}))=varargin{ii};

end

You could use load, but you mention this and seem unhappy with this option. If you want to write your own functions, you could do:


function [] = struct2var(M)
F = fieldnames(M)
for ii = 1:length(F)
assignin('caller',F{ii},M.(F{ii}));
end


and for the reverse op:

function [M] = var2struct(varargin)
for ii = 1:length(varargin)
M.(inputname(ii)) = varargin{ii};
end


Note that there may be some typo's in the above as I did not test them but they should get you there.
