How to save the output of loop function with different names?

EXPORTGRAPHICS Save plot or graphics content to file EXPORTGRAPHICS(OBJ, FILESPEC) saves the specified graphics to a file. OBJ is the handle of any type of an axes, a figure, a chart that can be a child of the figure, a tiled chart layout, or a container within the figure. FILESPEC is a character vector or string scalar specifying the name of a file to create. It must include the extension, and can optionally include a full or relative path. EXPORTGRAPHICS supports creating JPEG, PNG, and TIFF images, and EPS, PDF, and EMF vector formats (EMF is only supported on Windows). EXPORTGRAPHICS(___, OPTIONS) saves the graphics to the file, applying the specified OPTIONS. OPTIONS is one or more of the following name-value pairs. 'ContentType', CONTENTTYPE how to generate content in vector format files CONTENTTYPE can be one of the following values - 'vector' to generate vectorized (scalable) output - 'image' to generate rasterized output (embed image) - 'auto' allow MATLAB heuristic to decide The default value is 'auto' 'Resolution', DPI specifies output resolution for images. DPI must be a positive whole number. The default value is 150 'BackgroundColor', COLORSPEC specifies the color to use as the background COLORSPEC can be one of the following values - a color name, such as 'red', or 'w' - an RGB triplet, such as [1 0 0] or [1 1 1] - a hexadecimal color code, such as '#FFF' or '#FFFFFF') - 'none' to use either a white or transparent background, depending on what the output format supports - 'current' to use the graphic's current background color The default value is 'white' 'Colorspace', COLORSPACE the color space to use when generating output COLORSPACE can be one of the following values - 'rgb' generates RGB true color output - 'gray' generates grayscale output - 'cmyk' generates cyan, magenta, yellow, black output The default value is 'rgb' 'Append', APPEND specifies whether to append the output to an existing file or replace the content. APPEND can have a value of true or false. - true appends the output to an existing file - false replaces the content in an existing file The default value is false Example: Export a plot to a pdf file plot(rand(3)); exportgraphics(gca, 'results.pdf'); Example: Export a plot to a pdf file and ensure output is vectorized/scalable plot(rand(3)); exportgraphics(gca, 'results.pdf', 'ContentType', 'vector'); Example: Export a plot as an image to a pdf file plot(rand(3)); exportgraphics(gca, 'results.pdf', 'ContentType', 'image'); Example: Export a plot and append to an existing pdf file plot(rand(3)); exportgraphics(gca, 'results.pdf', 'Append', true); Example: Export a specific plot from the figure fig = figure; ax1 = subplot(2,1,1); bar(magic(4)); ax2 = subplot(2,1,2); plot(rand(4)); exportgraphics(ax2, 'results.png'); Example: Export all plots from figure to an image file at 300DPI subplot(2,1,1); bar(magic(4)); subplot(2,1,2); plot(rand(4)); exportgraphics(gcf, 'results.png', 'Resolution', 300); Example: Export a plot to an image file with a red background plot(rand(3)); exportgraphics(gca, 'results.png', 'BackgroundColor', [1 0 0]); Example: Export a plot to a grayscale image file plot(rand(3)); exportgraphics(gca, 'results.png', 'Colorspace', 'gray'); See also COPYGRAPHICS, EXPORTAPP Documentation for exportgraphics doc exportgraphics
