Ask Question Asked 2 years, 11 months ago. Active 2 years, 11. I recommend changing the Fortran to write a text file, and have Matlab read the text file.
I can write to a file, but it writes to the file in scientific notation. I am basically after a file with about 2048 lines of 16-bit ones and zeros or alternatively, just in standard form as in: 32767 -32768 not 3.2767e -4.
I am a little new to writing matlab function files. I need to write a function file that, takes in either a binary or decimal and converts it to either decimal or binary respectively. The program should first ask whether to convert to binary or decimal.
Read the Data. The Binary File Reader block reads the data in binary file Matdata.bin into 4 channels, with each channel containing 5 samples. The File header parameter of the reader specifies the header of the data. If the exact header is not known, you must at least specify the prototype of the header, that is, its size and data type.
Write the binary image to a file in 1-bit format. If the file format supports it, imwrite exports a binary image as a 1-bit image, by default. To verify this, use imfinfo to get information about the newly created file and check the BitDepth field. When writing binary files, imwrite sets the ColorType field to grayscale.
The Binary File Writer and Binary File Reader blocks do not support writing and reading fixed-point data. As a workaround, you can write the stored integer portion of the fi data, read the data, and use this value to reconstruct the fi data.
I personally like UltraEdit, which has a binary view. You could also read the file in chunks like I told you before to verify the file. This advice is an effort to figure out where the problem lies: LabVIEW writing the file or Matlab reading the file. If the file is verified, then the problem is with Matlab.
Arguments con. Binary connection from which the MAT file structure should be read. If a character string, it is interpreted as filename, which then will be opened (and closed afterwards). If a raw vector, it will be read via as a raw binary connection. maxLength. The maximum number of bytes to be read from the input stream, which should be equal to the length of the MAT file structure.
