Hello I have the following character array,
val =
3×79 char array
' 0.24971474E+01 0.17808300E-02-0.78001300E-06 0.14843700E-09-0.10340100E-13 '
'-0.68234235E+03 0.12869436E+01 0.34385300E+01 0.14431400E-03-0.10819100E-06 '
' 0.21683900E-09-0.55430700E-13-0.10374900E+04-0.39268200E+01 '
I want to be able to store all the numbers in a vector but str2num does not sem to work seeing as if the number is negative, there are no spaces between them. Each number occupies 15 spaces. I thought of adding a space at given columns but I'm not sure that is the best way to do this. I also want to avoid loops and do all three rows at once. If anyone can help and suggest what to use I'll be really thankful!

"I want to be able to store all the numbers in a vector ..."
That is easy with sscanf:
>> vec = sscanf(val.','%f')
vec =
2.4971e+00
1.7808e-03
-7.8001e-07
1.4844e-10
-1.0340e-14
-6.8234e+02
1.2869e+00
3.4385e+00
1.4431e-04
-1.0819e-07
2.1684e-10
-5.5431e-14
-1.0375e+03
-3.9268e+00
