How to create an array with the same letter but different number

Hi,

How can I create an array or cell, something like Variable = {'X1','X2','X3',...,'X43'}? when i give for example the length = 43.

So when I do my plots, i call put the title as title (variable(i))

Thanks!

[Adam]

Variable = arrayfun( @(x) ['X', num2str( x )], 1:43, 'UniformOutput', false )

would create them all upfront.

Answer 1

Len = 43;
V   = sprintfc('X%d', 1:Len);

Or with modern Matlab versions:

V = compose('X%d', 1:Len);

Then:

title(V{i})

Answer 2

for i = 1:10
    plot(rand(1,10))
   title(sprintf('X%d',i))
   drawnow
   pause(0.5)
end

+1: There is no need to store the names in an array, if you can create them dynamically.
