Unformatted text preview: Data Files MAT Files-- memory efficient binary format-- preferable for internal use by MATLAB program ASCII files-- in ASCII characters-- useful if the data is to be shared (imported or exported to other programs) MATLAB Input To read files in if the file is an ascii table, use load if the file is ascii but not a table, file I/O needs fopen and fclose Reading in data from file using fopen depends on type of data (binary or text) Default data type is binary Save Files 8-digit text format (variable list) save <fname> <vlist> - ascii 16-digit text format save <fname> <vlist> - double Delimit elements with tabs save <fname> <vlist> - double - tabs Example : Vel = [1 3 5; -6 2 -3] save velocity.dat Vel-ascii 1.0000000e+000 3.0000000e+000 5.0000000e+000-6.0000000e+000 2.0000000e+000 -3.0000000e+000 Load Files Read velocity into a matrix velocity.dat >> load velocity.dat >> velocity velocity = 1 3 5-6 2 -3 1.0000000e+000 3.0000000e+000 5.0000000e+000-6.0000000e+000 2.0000000e+000 -3.0000000e+000...
