Textscan of a vector with spaces ("32")

Hi,

I have a vector:

Msg=[ 32 52 68 32 50 69 32 51 50 32 52 32 48 32 48 ...]

Now I want to make a textscan and write all values which are separated with a space ("32") and write them into a cell array.

Info: "Msg" is only one vector from an incomming Data matrix.

Question: How can i use the syntax "textscan" for my incomming data, or is there another syntax for scanning a vector for scaces("32") and write them into a cell array?

The simplest way is probably:

c = strsplit(char(Msg), ' ')

If you want c to still contain ascii values instead of the corresponding characters:

c = cellfun(@double, strsplit(char(Msg), ' '), 'UniformOutput', false)

Thank you for the answer, works good.

Can I change the Type in this step into a decimal

I'm afraid I don't understand what you mean by Type. Can you show an example of the result you want?

Throug the cellfun,I have a cell with:

c= [52 68] [50 69] [51 50] [52] [48] [48]

Now I converted them into a char with:

 c = cellfun(@char, strsplit(char(ReceiveMsg), ' '), 'UniformOutput', false);

c= [4D] [2E] [32] [4] [0] [0]

but I want to have the decimal of the cells:

c=[77] [46] [50] [4] [0] [0]

[Guillaume]

Note, in your example just above, the cellfun is completely unnecessary since the output of strsplit is already char.

c = strsplit(char(ReceiveMsg), ' ') %does just the same

To convert these hexadecimal values to numbers, use hex2dec:

c = hex2dec(strsplit(char(ReceiveMsg), ' '))
