how to read the data of type a*b?

I have input dataset of following type:

'1*5 5*4 6 8 3 12 -5 9*0 7*-1'

how can I read each value and store it in nice format.

"how can I read each value and store it in nice format."

What is the expected output for that example?

[Mahendra Yadav]

The output should be an array by consisting all the elments. Like for above input dataset, the output should look like that

x = [1, 5, 5, 4, 6, 8, 3, 12, -5, 9, 0, 7, -1]

Answer 1

[Stephen23]

str = '1*5 5*4 6 8 3 12 -5 9*0 7*-1';
vec = sscanf(str,'%f%*[ *]',[1,Inf])

vec = 1×13

1 5 5 4 6 8 3 12 -5 9 0 7 -1

Taking a wild guess that the ‘multiiplicatiion’ operators are equivalent to the ‘power-of-10’ indicator ‘E’ or ‘e’, first use strrep then strsplit then str2double (here done in a single line) —

format shortG
str = '1*5 5*4 6 8 3 12 -5 9*0 7*-1';
num = str2double(strsplit(strrep(str, '*', 'E'), ' '))

num = 1×9

1.0e+00 * 1e+05 50000 6 8 3 12 -5 9 0.7

I have no iidea if this is actually correct.

Dear S. Strider,

Accutally It's not correct. The above output is not consisting all the elements. Like for the above input dataset, the output should look like that:

x = [1, 5, 5, 4, 6, 8, 3, 12, -5, 9, 0, 7, -1]

[Star Strider]

In that instance, then just this —

format shortG
str = '1*5 5*4 6 8 3 12 -5 9*0 7*-1';
num = str2double(strsplit(str, {' ','*'}))

num = 1×13

1 5 5 4 6 8 3 12 -5 9 0 7 -1

Avoid all tthe complications.

I didn’t see this earlier because I was sleeping. I’m in the UTC-7 timezone.
