I have several variables that are in row form. I would like to write a script that will transpose these variables into column form and then combine write them into one csv file with each variable in a separate row. I have been able to export them individually in row form using csvwrite, but I'm not sure if I'm able to manipulate and combine variables with this or if I need to use writematrix instead. However, when I try to use this, it gives me the error: Undefined function or variable 'writematrix'.

If you want each variable as a row, why would you transpose them in the first place? Also, please show the code you've tried, and give an example of input and intended output.

The function writematrix is available in R2019a.

Hi,

If you have a vector or matrix X, you can use the : symbol to flatten it into a column vector. Supposing you have several row/column vectors of equal length, you can put them all as columns in a matrix like this:

[vec1(:), vec2(:), vec3(:)]

Alternatively, you can structure your data as a table, then use the function writetable.
