● A = importdata('filename'),将filename中的数据导入到工作区中,并保存为变量A; ● importdata('filename','delimiter'),将filename中的数据导入到工作区中,以delimiter指定的符号作为分隔符; 例13-2 从文件中导入数据。 >> imported_data = importdata('matlab.mat') imported_data = ans: [1.1813 1.0...
Close the file. fclose(fileID); Append Data to Binary File Write a binary file containing the elements of the 4-by-4 magic square, stored as double-precision floating-point numbers. fileID = fopen('magic4.bin','w'); fwrite(fileID,magic(4),'double'); fclose(fileID); ...
1.1.1、save FileName 变量1 变量2 … 参数 |-将工作空间中的数据存放到MAT数据文件 |-变量1、变量2可以省略,省略时则保存工作空间的所有变量;参数为保存的方式,有-ASCII、-append等方式。 1.1.2、load FileName 变量1 变量2… |-从数据文件中取出变量存放到工作空间 ...
I have a data file with several arrays of financial data, prices, interest rates, etc on 43 different stocks, i'd like to add more data so that the data is up to date. Is there any way to append more data to the end of my current dat...
Matlab数据导入导出方法
● importdata('filename','delimiter'),将filename中的数据导入到工作区中,以delimiter指定的符号作为分隔符; 例13-2 从文件中导入数据。 >> imported_data = importdata('matlab.mat') imported_data = ans: [1.1813 1.0928 1.6534] A: [2x3 double] ...
7、ata(filename,delimiter),将filename中的数据导入到工作区中,以delimiter指定的符号作为分隔符;例13-2 从文件中导入数据。 imported_data = importdata(matlab.mat)imported_data = ans: 1.1813 1.0928 1.6534 A: 2x3 double I_q: 415x552x3 uint8 num_of_cluster: 3与load函数不同,importdata将文件中的...
