Matlab文件操作示例
問題1:如何在matlab中讀取數(shù)據(jù)文件將如下格式的數(shù)據(jù)文件data.txt裝載到內(nèi)存中,并生成一個二維數(shù)組1 0.0002 22 0.0004 33 0.3 4輸入命令“l(fā)oad -ascii data.txt”,此時數(shù)組data已經(jīng)存在,輸入命令“data”可以察看data>> load -ascii data.txt>> datadata =1.0000 0.0002 2.00002.0000 0.0004 3.00003.0000 0.3000 4.0000>> 問題2:如何將數(shù)組的數(shù)據(jù)保存到數(shù)據(jù)文件?Use the Save command.Save the data in ASCII form using the save
command with the -ascii option. For example,A = rand(4,3);save temp.dat A -asciicreates an ASCII file called temp.dat containing1.3889088e-001 2.7218792e-001 4.4509643e-0012.0276522e-001 1.9881427e-001 9.3181458e-0011.9872174e-001 1.5273927e-002 4.6599434e-0016.0379248e-001 7.4678568e-001 4.1864947e-001
