Hi everyone,

I have a structure (DATA) with 3 fields (name, folder, data (tables)). There are many rows with names (field name) in a pattern as follows :

'London_FirstVariable_Water.txt'

'London_SecondVariable_Fire.txt'

'London_ThirdVariable_Air.txt'

'London_FourthVariable_Earth.txt'

'Paris_FirstVariable_Water.txt'

'Paris_FourthVariable_Fire.txt'

'Paris_FifthVariable_Air.txt'

'Paris_ThirdVariable_Earth.txt'

etc.

I want to make a new structure that keeps only the rows with 'XXX_XXX_Fire.txt', no matter what is before.

I have tried this :

FIRE = DATA(strcmp({DATA.name}, '%s_%s_Fire.txt'))

which obviously doesn't work.

However, it works like this :

FIRE = DATA(strcmp({DATA.name}, 'London_SecondVariable_Fire.txt'))

but this way I only get this one row, and I would rather not have to write each name in separate lines but something to get all the rows with a name containing Fire.txt

Any idea ?

Thanks for your help :)

@Loriann Chevalier: you then use that logical vector as a logical index to remove the parts of the array/s that you do not want. Much like you showed in your question.
