textread a column of data with mixed data types

Dear,

I have a column of data, some of them are of "%E" while the others are of "%f"... these two types of data are mixed up in the column. Now, I'd like to "textread" my data, and of course, neither textread('mydata.csv','%f'...) nor textread('mydata.csv','%E'...) works.

Could you please help me?

A synthetic example of the data would help.
