Dot indexing is not supported for variables of this type.

sh_16_data = importdata("M006_A_Shaker_16.txt");

sh_16_freq = sh_16_data.data(:,2)

Data:

1.000 25.000 10.430 2.848

2.000 26.000 13.824 2.705

3.000 27.000 18.449 2.130

4.000 28.000 20.689 1.098

5.000 29.000 18.676 0.500

I am trying to take the second column as a variable but it immediately gives me the "Dot indexing is not supported for variables of this type."

Any help is appreciated.

Try readmatrix instead.

If you have any more questions, then attach your data (text file) with the paperclip icon after you read this:

You are assuming that sh_16_data is a structure.

Instead, do

sh_16_freq = sh_16_data(:,2)
