How do I write two strings to the same line using dlmwrite?

Dear Matlab Community

I am having trouble using dlmwrite (and maybe dlmwrite is not the right tool here!) to write a variable number of strings to one line in .dat file.

I think the issue is best illustrated by an example.

I am writing data processed in Matlab to a text file (.dat format). In the first two columns I always write a number and a string, e.g.

no. SN-curve

107 'Curve-D'

In the columns following these first two, i write a variable number of numbers (directions, sorted in a vector), e.g.

no. SN-curve Direc Direc Direc Direc Direc

107 'Curve-D' 0.00 30.0 60.0 90.0 120.0

The final column of the line must contain a number (a time to failure, i.e. lifetime of a component), that is always placed on the same position, i.e. the number of blanks between '120' and the final number is variable and depends on the number directions, e.g.

no. SN-curve Direc Direc Direc Direc Direc LIFE

107 'Curve-D' 0.00 30.0 60.0 90.0 120.0 75 108 'Curve-D' 0.00 30.0 60.0 90.0 92

So for no. 108 only four directions exist, but the lifetime must be aligned.

I hope that I made the issue clear :-)

Thanks in advance, Poul

no. SN-curve  Direc  Direc  Direc  Direc  Direc   LIFE

107 'Curve-D' 0.00   30.0   60.0   90.0   120.0     75

108 'Curve-D' 0.00   30.0   60.0   90.0             92

I think the format was lost somewhere, hopefully this looks better...

Problem solved by building vector in a loop and writing the whole thing in one go.
