Matlab文件操作示例

問(wèn)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(gè)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(shí)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(wèn)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
