I\'m working with MATLAB for few days and I\'m having difficulties to import a CSV-file to a matrix.
My problem is that my CSV-file contains almost only Strings and
I recommend looking at the dataset array.
The dataset array is a data type that ships with Statistics Toolbox. It is specifically designed to store hetrogeneous data in a single container.
The Statistics Toolbox demo page contains a couple vidoes that show some of the dataset array features. The first is titled "An Introduction to Dataset Arrays". The second is titled "An Introduction to Joins".
