I have a cell array with values like e-.00085 and 8.5e-4. I am trying to replace the 'e' with nothing '' in the value with the leading e, while leaving the scientific notation e alone.
x = ['e-.00085';'8.5e-4'];
strrep(x,'e','');
desired_final_ans = ['-.00085';'8.5e-4'];
Is there a way to determine in an if statement whether the cell begins with an 'e'?

Ran in:
x = {'e-.00085';'8.5e-4'}
x = 2×1 cell array
{'e-.00085'} {'8.5e-4' }
regexprep(x, '^e', '')
ans = 2×1 cell array
{'-.00085'} {'8.5e-4' }

Ran in:
x = {'e-.00085';'8.5e-4'};
y = strrep(x,'e','')
y = 2×1 cell array
{'-.00085'} {'8.5-4' }
