I have the string array named Colores, and I want to convert it to a 7x3 numerical array I can use to pass RGB values to scatter plotting functions. I am stuck here. Can anyone please help?
Colores 7×1 string array
"0 0 0.17241"
"0 0 1"
"0 0 1"
"0 0 1"
"0 0 1"
"1 0.82759 0"
"0 0 1"
"1 0.82759 0"

Ran in:
Colores = ["0 0 0.17241"; "0 0 1"; "0 0 1"; "0 0 1"; "0 0 1"; "1 0.82759 0"; "0 0 1"; "1 0.82759 0"]
Colores = 8×1 string array
"0 0 0.17241" "0 0 1" "0 0 1" "0 0 1" "0 0 1" "1 0.82759 0" "0 0 1" "1 0.82759 0"
fprintf('%s\n', Colores)
0 0 0.17241 0 0 1 0 0 1 0 0 1 0 0 1 1 0.82759 0 0 0 1 1 0.82759 0

Ran in:
S = ["0 0 0.17241"; "0 0 1"; "0 0 1"; "0 0 1"; "0 0 1"; "1 0.82759 0"; "0 0 1"; "1 0.82759 0"]
S = 8×1 string array
"0 0 0.17241" "0 0 1" "0 0 1" "0 0 1" "0 0 1" "1 0.82759 0" "0 0 1" "1 0.82759 0"
M = double(split(S))
M = 8×3
0 0 0.1724 0 0 1.0000 0 0 1.0000 0 0 1.0000 0 0 1.0000 1.0000 0.8276 0 0 0 1.0000 1.0000 0.8276 0
