Selecting part of a string

I have a list of file names in a variable called file_name e.g:

[a.txt b.txt c.txt d.txt]

I would like to create a new variable which only contains:

[a b c d]

Is this possible?

Thanks in advance Matt

Hi Matt,

is your file_name variable just one string like

file_name = ['a.txt' 'b.txt' 'c.txt' 'd.txt']?

[Matt]

I'm not sure what you mean, it is a 4x1 matrix (4 rows, 1 column).

Thanks,

Matt

You say 4 rows and 1 column but your example is 4 columns and 1 row

[Paulo Silva]

surely not the best way to do it but here is my way

v=['a.txt' 'b.txt' 'c.txt' 'd.txt']
cell2mat(arrayfun(@(x)strtok(x,'.txt'),v,'uni',false))

or

v=['a.txt' 'b.txt' 'c.txt' 'd.txt']'
cell2mat(arrayfun(@(x)strtok(x,'.txt'),v,'uni',false))

Hi,

I'm getting the following error for both of the above methods

"Cannot support cell arrays containing cell arrays or

objects."

Thanks,

Matt

The following kind of works:

arrayfun(@(x)strtok(x,'.txt'),file_list,'uni',false)

but in the new variable there are quotes around the text e.g

'a.txt' is it possible to remove the quotes?

Hi,

this works perfectly:

x = strtok(file_list,'.txt')

thanks,

Matt
