If you have used FORTRAN, you will know that FORTRAN's formatted reading allows you to directly specify the number of characters to be read and their positions. These characters include spaces. If a variable in the specified position encounters a space, FORTRAN will automatically assign zero. However, in MATLAB, if formatted reading encounters a space, it will simply skip it. Is there any method to make MATLAB read in a way similar to FORTRAN?

Yes.
Use the fixedWidthImportOptions function to define the field widths, then use that in conjunction with readtable to read the file.
It can be a bit of a challenge (and requires some experimentation) when initially encountered, however it definitely works.

A much easier approach is to call DETECTIMPORTOPTIONS with its option "FileType" set to "fixedwidth".
Read this discussion to know why:
