How to load and read a mat file in matlab.

Reading them in is definitely the easy part. The load command requires that the data in the file be organized into a rectangular array. The simplest though least flexible procedure is to use the load command to read the entire contents of the file in a single step. Name of file specified as a character vector or string scalar.

You can get the file used in this post here. Filename can include a file extension and a full or partial path. Really appreciate any insight on this. A structure is like a box.

The matlab load command. No column titles are permitted. It is fine to load small mat file but when i try to load ones that s several hundreds of mb it will not succeed until i restart the matlab which is an annoying issue. When you wish to access your data you first need to get it out of the structure just like you would get something out of the box before you can use it.

The structure s is not your original data array but a container that contains your data array. There is more than one way to read data into matlab from a file. Coming from the academia the annotations for the dataset was in the mat format. The third and fourth variables topomap1 and topomap2 are both arrays containing topography data load the elevation data from the third column of each variable into a field of the structure array s for each field specify a field name that is the original variable name prefixed by elevationof.

If you do not specify filename the load function searches for a file named matlab mat.
