Creating an ordered list of vectors

I'm looking to create a list of vectors arbitrary in length. I was looking for something along the lines of: iterations=___ % some arbitrary number

for i=1:iterations vi=[1 2 3 4]; end

Hoping this would create the vectors v1, v2, v3, v4 ... which are all the same vector [1 2 3 4].

Please do not do that. Please read this FAQ

the problem is I need each vector to do a different task. I was trying to avoid having to creating higher ordered arrays. I'll work it out tho!

Generating full variable names is nearly always trouble. Use cell arrays or use a structure with dynamic field names.

[Walter Roberson]

T1 = cellstr(num2str((1:iterations).','v%d')).';

T2 = repmat({[1 2 3 4]},1,iterations);

T = [T1;T2];

VVars = struct(T{:});

Then use VVars.v1, VVars.v2, VVars.(sprintf('v%d',192)) and so on.

Use a CELL instead:

v = cell(1, iterations);
v(:) = {1:4}

Now you can use v{1} instead of v1. It is always better (nicer, safer, faster) to use an index as index, instead of hiding the index in the name of the variable.

v=perms(1:4);

Now instead of having v1,v2... you have v(1),v(2)...

Why PERMS? The OP looks for v1=[1,2,3,4] etc.
