Hello everyone. I have a file .data and I need to convert it to an array. How can this be done?

I opened the file using "importdata" function, but it was created as a cell and I need it to be an array because I will applying the Principal component analysis.

The data in this file appears in this format

'5.1,3.5,1.4,0.2,Iris-setosa'

'4.9,3.0,1.4,0.2,Iris-setosa'

'4.7,3.2,1.3,0.2,Iris-setosa'

'4.6,3.1,1.5,0.2,Iris-setosa'

I'm using the Iris flower data set or Fisher's Iris data set, this is a multivariate data set that consists of 50 samples from each of three species of Iris (Iris setosa, Iris virginica and Iris versicolor).

Use the recommended data import fcns, such as readtable() or readmatrix() that would import your data into a Table or Matrix array, respectively.
