how to convert a string to a vector

Hi I have a string chain and wish to convert it into a vector So if my input is: x =1,3,3,4,5,6,6 I need an output

y = [1 3 3 4 5 6 6] How do I do this?

Answer 1

[per isakson]

One way

>> str ='1,3,3,4,5,6,6'
str =
1,3,3,4,5,6,6
>> num = textscan( str, '%f', 'Delimiter',',' )
num = 
    [7x1 double]

and together with the missing step

str ='1,3,3,4,5,6,6';
num = textscan( str, '%f', 'Delimiter',',' );
num = permute( num{1}, [2,1] )
num =
     1     3     3     4     5     6     6

another way

>> str2num( str )
ans =
     1     3     3     4     5     6     6

I have the result in the form of columns

Are you indicating that your input is a string that has newlines and words like "Columns 326 through 338" inside it, or are you discussing what the output looks like after textscan or str2num?

If your input is a string like that, "Don't do that", get access to the original data instead.

[lamghari]

No, i am discussing what the output looks like after str2num my input is for example:

6,7,6,6,6,6,6,5,4,4,4,4,3,4,4,4,4,4,5,5,4,5,5,5,6,5,6,6,6,6,6,5,5,4,4,5,4,4,5,4,4,4,4,4,4,4,4,3,4,4,3,6,6,1,0,0,7,0,0,0,0,0,0,0,0,1,0,0,1,0,0,1,0,0,0,7,6,7,7,6,5,1,0,0,0,0,0,0,1,0,0,0,0,1,0,1,1,1,1,1,2,1,2,2,3,2,2,3,3,3,4,3,2,2,2,2,2,3,2

i need an output:

y = [6 7 6 6 6 6 6 5 4 4 4 4 3 4 4 4 4 4 5 5 4 5 5 5 6 5 6 6 6 6 6 5 5 4 4 5 4 4 5 4 4 4 4 4 4 4 4 3 4 4 3 6 6 1 0 0 7 0 0 0 0 0 0 0 0 1 0 0 1 0 0 1 0 0 0 7 6 7 7 6 5 1 0 0 0 0 0 0 1 0 0 0 0 1 0 1 1 1 1 1 2 1 2 2 3 2 2 3 3 3 4 3 2 2 2 2 2 3 2]

[per isakson]

"How do I do this?" &nbsp The short answer is: You cannot do that. And that's because

y = [6 7 6 6 6 6 6 5 4 4 4 4 ... ]

isn't a display format. It's an example of an assignment of a numerical vector to a variable, y

[lamghari]

ok.thank you very much

[Walter Roberson]

output = ['y = [', regexprep(num, ',', ' '), ']' ];

If what you want is the string 'y = [6 7 6 6 6 6 6 5 4 4 4 4 ... ]'
