I have many files that are large where the first row is a header row. The files are tab delimited and I want to import only selected columns. All theses vectors are numeric but the missing value is a dot (.) . I want to import these selected columns where the name of each vector is the name of the header and I want my vectors to be numeric. Any clue about how to do it?

v=importdata('your_file.txt')

it is taking the data as cell which will deprive me from naming the vectors after the 1st row. For example. I am getting under v.textdata:
'ENTITY' 'CALL8786' 'RCFDA000' 'RCFDA001' 'RCFDA002' 'RCFDA003'
'37' '2' '0' '0' '0' '.'
'242' '2' '0' '0' '0' '.'
