How to read floating point number 5.3246-5 as 5.3246E-5 in text file

I want to read 9.4345-51.8998772.518305 in a text file as 9.4345E-5, 1.899877, 2.518305 by recognizing it as a different number by 8 characters. When I use the '%8f' option in sscanf, it reads as 9.4345, -51.8998, 772.5183.

Is there any way? Please.

str = '9.4345-51.8998772.518305';
tmp = cellstr(reshape(str,8,[]).');
tmp = regexprep(tmp,'(?<=\d)([-+]\d+)$','E$1')

tmp = 3×1 cell array
    {'9.4345E-5'}
    {'1.899877' }
    {'2.518305' }

vec = str2double(tmp)

vec = 3×1

9.4345e-05 1.899877 2.518305
