How to split this?

I have M as a result of another function.

and I have to split M like C automatically...

I want to split it every 16 bits.

M => input split function => output C

M = '01100001011000100110001110000000000000000000000000000000000000000000000000000000'

????

C = {'0110000101100010'; '0110001110000000'; '0000000000000000'; '0000000000000000';'0000000000000000';}

how to make it? I'm stuck on this problem...

can you help me?

C = reshape(M, 16,[])'

C =

  5×16 char array

    '0110000101100010'
    '0110001110000000'
    '0000000000000000'
    '0000000000000000'
    '0000000000000000'
    

If you need it to end up as a cell array or chars, you can wrap it in cellstr:

C = cellstr(reshape(M, 16,[])')

C =

  5×1 cell array

    {'0110000101100010'}
    {'0110001110000000'}
    {'0000000000000000'}
    {'0000000000000000'}
    {'0000000000000000'}

Did you try a simple for loop:

M = '01100001011000100110001110000000000000000000000000000000000000000000000000000000'
counter = 1;
for index1 = 1 : 16 : length(M)
	index2 = min(length(M), index1 + 15);
	c{counter} = M(index1 : index2);
	counter = counter + 1;
end
celldisp(c)

Note: This robust, general purpose loop works even if M is not a multiple of 16 characters. Otherwise (if it is known to be a multiple of 16) I'd use reshape().

You could make a matrix

newMatrix=reshape(M(1:floor(length(M)/16)*16),16,[])';

Answer 4

[Walter Roberson]

temp = textscan(M,'%16s');
C = temp{1};

This handles M that are not multiples of 16 characters.

Note, though, that if M contains whitespace, that it will not split by 16 character groups, and would instead treat each "word" as the beginning of a section to be split.
