Example 1:Using TEXTREAD to read in an entire file into a cell array % This command readsinthe file fft.m into the cell array, file file = textread('fft.m','%s','delimiter','\n','whitespace',''); CODE: Example 2:Using STRREAD to read the words in a line % This command uses ...
NumChannels (number of columns in the data matrix) set to 1. Create a dsp.BinaryFileWriter object using this header. The object writes the header first, followed by the data, to ex_file.bin. The data is a noisy sine wave signal. View the data in a time scope. Get L = 150; hea...
Write a nine-element vector to a sample file, nine.bin. fileID = fopen('nine.bin','w'); fwrite(fileID,[1:9]); fclose(fileID); Read all the data in the file into a vector of class double. By default, fread reads a file 1 byte at a time, interprets each byte as an 8-...
CSVREAD用来读分隔符是逗号的文件,是DLMREAD的特殊情况。当读空格和Tab分隔的电子数据表文件时,DLMREAD特别有用。以'sample_file.txt'为例: Example 1: Using DLMREAD to read in a file with headers, text, and numeric data % This reads in the file '...

MATLAB always stores data into column major. But as workaround to this issue you can read the file as 2 rows and multiple columns and transpose the matrix to get expected result. For example the file can be read as: 테마복사 fileID = f...
The FREAD function can read data from binary files and store the data into a matrix. Its call format is: [A, COUNT]=fread (FID, size, precision) Note: the A is used for storing the read data matrix, COUNT is the data returned by the read element number, FID, size file han...
