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

9 views (last 30 days)
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).

websave("iris.dat", "https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data")
ans = '/users/mss.system.N88I3a/iris.dat'
x = readtable("iris.dat")
x = 150×5 table
Var1 Var2 Var3 Var4 Var5 ____ ____ ____ ____ _______________ 5.1 3.5 1.4 0.2 {'Iris-setosa'} 4.9 3 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'} 5 3.6 1.4 0.2 {'Iris-setosa'} 5.4 3.9 1.7 0.4 {'Iris-setosa'} 4.6 3.4 1.4 0.3 {'Iris-setosa'} 5 3.4 1.5 0.2 {'Iris-setosa'} 4.4 2.9 1.4 0.2 {'Iris-setosa'} 4.9 3.1 1.5 0.1 {'Iris-setosa'} 5.4 3.7 1.5 0.2 {'Iris-setosa'} 4.8 3.4 1.6 0.2 {'Iris-setosa'} 4.8 3 1.4 0.1 {'Iris-setosa'} 4.3 3 1.1 0.1 {'Iris-setosa'} 5.8 4 1.2 0.2 {'Iris-setosa'} 5.7 4.4 1.5 0.4 {'Iris-setosa'}

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