constructing sequence of ismember

Hi all,

I have the vector A=

‘l1’

‘l2’

‘Kl9’

‘E9’

…

In my case, A contains hundreds of different elements (‘l1’,‘l2’,…). I want to produce a series of

lopp(ismember(c,{'x' })) where x stands for each element of A So I want to have

B=[ lopp(ismember(c,{'l1' })) lopp(ismember(c,{'l2' })) lopp(ismember(c,{'KI9' })) lopp(ismember(c),{'E9' }))…]

Is there any code that will enable me to construct B automatically

 thanks

[tf, idx] = ismember(c, A);
B =  lopp(idx(tf))

HI walter, for some reason I do not get the same result

[antonet]

Just to say that c is a vector

[Walter Roberson]

I will cross-check later when I'm at my desk.

[antonet]

I really t thank you.

[Walter Roberson]

Try

[tf, idx] = ismember(A,c);

B = lopp(idx(tf));

[antonet]

Hi walter. Again, the results are not the same

[antonet]

to clarify some things. the vector c is

'l1'

'l1'

'l1'

'l1'

'l1'

'l1'

'l1'

'l1'

'l1'

'l2'

'l2'

'l2'

'l2'

l3'

'l3'

'l3'

'l3'

'l3'

and the lopp is

[11.9154]

[11.4014]

[10.8762]

[10.5987]

[10.2064]

[10.0170]

[10.3118]

[10.9467]

[11.4735]

[11.2132]

There are repeats in c ? Hmmm, I'll have to think about this a bit more.

[antonet]

yes i have repeated l1s l2s l3s l4s and l5s in c. thank you again
