My 400*400 array looks like this.
I want to truncate those exponential 'e'values from the array. for example 3.7267e-04 to 3.7267
Thanks in advance.

See the documentation on format (link).

Just on a chance that you want the mantissa but no exponent:
a=[1.2e-6, 3.4e-7, 8.9e-10]
exponents = ceil(log10(a))-1
out = a .* 10.^exponents % Numerical values

You can consider any value less than 1e-15 as essentially 0. It's just truncation error.
