mget - reads byte or word in a given binary format and convert to double

mgeti - reads byte or word in a given binary format return an int type

### Calling Sequence

  `x=mget([n,type,fd])`
  `x=mgeti([n,type,fd])`

### Parameters

- `n`:a positive scalar: The number of items to be read.
- `fd`: scalar. The `fd` parameter returned by the function `mopen`. -1 stands for last opened file. Default value is -1.
- `type`: a string. Give the binary format used to write all the entries of x.
- `x`: a vector of floating point or integer type numbers

### Description

The `mget` function reads data in the input specified by the stream parameter `fd` and returns a vector of floating point data. The `mgeti` function reads data in the input specified by the stream parameter `fd` and returns a vector of integer data.

Data is read at the position at which the file pointer is currently pointing and advances the indicator appropriately.

The `type` parameter is a conversion specifier which may be set to any of the following flag characters (with default value "l"):

WARNING, when reading binary files under Windows to not forget to open the file with the `b` option like `fd1=mopen(file1,'rb')` if not the file will be interpreted as text file and the bytes with value `13` will be interpreted as newlines and ommitted.

  "l", "i", "s", "ul", "ui", "us", "d", "f", "c", "uc": for reading respectively a long, an int, a short, an unsigned long, an unsigned int, an unsigned short, a double, a float, a char and an unsigned char. The bytes which are read are automatically swapped if necessary (by checking little-endian status). This default swapping mode can be suppressed by adding a flag in the `mopen` function. Format "l", "d" and "f" are valid only with the `mget` function.
  "..l" or "..b": It is also possible to read in little-endian or big-endian mode by adding a 'l' or 'b' character at the end of a type specification. For example "db" will read a double in big-endian mode.

### Examples

        file1 = 'test1.bin';
        file2 = 'test2.bin';
        fd1=mopen(file1,'wb');
        fd2=mopen(file2,'wb');
        mput(1996,'ull',fd1);
        mput(1996,'ull',fd2);
        mclose(fd1);
        mclose(fd2);

        fd1=mopen(file1,'rb');
        if 1996<>mget(1,'ull',fd1) ;write(%io(2),'Bug');end;
        fd2=mopen(file2,'rb');
        if 1996<>mget(1,'ull',fd2) ;write(%io(2),'Bug');end;
        mclose(fd1);
        mclose(fd2);
