how to solve this reshape error?

reading the data

a=dlmread('S11.txt')

freq=a(:,1)

Sparameter=a(:,2)

Sparameter=reshape(Sparameter,1,21])

dlmwrite('output.csv',Sparameter,'-append')

like this i will be generating lot of text files

but i am getting reshaping error as no of elements changed so what changes i should make in my code so that how much ever no elements are present in text files i will be able to reshape and store it in excel sheet.

Sparameter=reshape(Sparameter,1,[]) %i want 1 row and multiple columns plz suggest if this s correct

Yes, this converts Sparameter into a row vector:

Sparameter=reshape(Sparameter,1,[])

However, since Sparameter is a column vector beforehand, from here:

Sparameter=a(:,2)

You can merely transpose it at that time instead of using reshape:

Sparameter=a(:,2).'
