例
// Preparing some data: H = rand(2,4,2); N = complex(rand(2,3), rand(2,3)); I = int8(grand(4,10,"uin",-100,100)); T = ["foo" "bar"]'; S = struct("num",H, "imag",N, "text",T, "int",I); C = {"Scilab", rand(2,3); H, S}; // Saving them: File = TMPDIR+"/matfile_listvar_example.mat"; savematfile(File,'-v7.3', 'H','N','I','T','S','C'); // Listing stored variables: fd = matfile_open(File); [names, classes, types] = matfile_listvar(fd); matfile_close(fd); sleep(1000) deletefile(File); names', classes', types' mprintf("The variable ""%s"" has type %d and class %d\n", names, types, classes)
--> names', classes', types' ans = !C H I N S T ! ans = 1. 6. 8. 6. 2. 4. ans = 21. 9. 1. 9. 22. 2. --> mprintf("The variable ""%s"" has type %d and class %d\n", names, types, classes) The variable "C" has type 21 and class 1 The variable "H" has type 9 and class 6 The variable "I" has type 1 and class 8 The variable "N" has type 9 and class 6 The variable "S" has type 22 and class 2 The variable "T" has type 2 and class 4
