You are using readmatrix to get a matrix (rather than a structure). You can add in new culumn to the matrix but not field.

Once the "dataAquisition" variable represent a import file matrix, from *.txt file, i need associate each field of the following array (validFields), to each column of INPUT.txt file.

In the first column i need made a count eac sample until reache the total of samples(this to garant all samples are readed).

On de second column whant increment each sample time aquisition that is preformed at each 0.008s( t= 1/fs).

can anyone give me some support?

Thanks in advance
