Mat file variable.

If filename is a mat file then s is a structure array. Por ejemplo load filename mat regexp mon tues o load filename mat regexp mon tues carga sólo las variables del archivo cuyos nombres comienzan con mon o tues. The primary advantage of using the matfile function over the load or save functions is that you can process parts of very large data sets that are otherwise too large to fit in memory. Cargue sólo las variables o campos cuyos nombres coincidan con las expresiones regulares expresiones regulares especificadas como vectores de caracteres o cadenas.

Example matobj matfile filename writable iswritable enables or disables write access to the file. Starting with mat file version 4 there are several subsequent versions of mat files that support an increasing set of features. P rand 1 10. If filename is an ascii file then load filename creates a double precision array containing data from the file.

In other words if a variable in your mat file is called a you can save over that variable with a new copy of a that you ve set to using the append option. You also can use command syntax to save the variables p and q. Create and save two variables p and q to a file called pqfile mat. S load loads data into s using any of the input arguments in the previous syntax group.

Load filename loads data from filename. Q ones 10. For mat files append adds new variables to the file or replaces the saved values of existing variables with values in the workspace. Save and load parts of variables in mat files you can save and load parts of variables directly in mat files without loading them into memory using the matfile function.

La principal ventaja de utilizar la función matfile en lugar de las funciones load o save es que puede procesar partes de conjuntos de datos muy grandes que de otro modo son demasiado grandes para caber en la memoria. If filename is a mat file then load filename loads variables in the mat file into the matlab workspace. Load filename mat treats filename as a mat file regardless of the file extension. Save pqfile mat p q matlab saves the variables to the file pqfile mat in the current folder.

Load filename mat variables loads the specified variables from filename. By default all save operations create version 7 mat files. The mat file object allows you to access and change variables directly in a mat file without having to load the variables into memory.
