replace a double in a array with a string BUT in specific Columns?
显示 更早的评论
Suppose the matrix is
A = [ 0.5 2 3 2.5 1 1
0.6 1 2 2.4 2 3
0.2 2 3 2.3 3 2]
My question is to replace 1 with so-so, 2 with Bad and 3 with good in 2nd and 3rd columns, and 1 with so-so, 2 with Bad and 3 with good in 5th and 6th column. I try to use num2cell, but cannot find out the way.
The output looks like this:
A = [ 0.5 bad good 2.5 so-so so-so
0.6 so-so bad 2.4 bad good
0.2 bad good 2.3 good bad]

>> AA = string([ 0.5 2 3 2.5 1 1
0.6 1 2 2.4 2 3
0.2 2 3 2.3 3 2])
A = strrep(AA(:,[2 3 5 6]),'1','so-so');
A = strrep(A(:,1:4),'2','bad');
A = strrep(A(:,1:4),'3','good');
AA(:,[2 3 5 6])=A;
A=AA
AA =
3×6 string array
"0.5" "2" "3" "2.5" "1" "1"
"0.6" "1" "2" "2.4" "2" "3"
"0.2" "2" "3" "2.3" "3" "2"A =
3×6 string array
"0.5" "bad" "good" "2.5" "so-so" "so-so"
"0.6" "so-so" "bad" "2.4" "bad" "good"
"0.2" "bad" "good" "2.3" "good" "bad" >>

Give an example of your desired output instead of description
