How To Get An Array From A Mat File Matlab
Hi i m working on image classification project using hue saturation and value histograms.
How to get an array from a mat file matlab. I can save the hue saturation and value histograms of six bins as six values for each histogram for each image. You can get the file used in this post here. Coming from the academia the annotations for the dataset was in the mat format. A structure is like a box.
Octave has matlab compatible save and load functions. And just like a box can contain something so can a structure hold your data. You may have a mat file that you want to read into scipy. Multidimensional arrays in matlab are an extension of the normal two dimensional matrix.
It looks like matlab is confused by the notation for the arrays and is trying to locate a class called e g. George sign in to comment. Generally to generate a multidimensional array we first create a two dimensional array and extend it. Or you want to pass some variables from scipy numpy into matlab.
Reading them in is definitely the easy part. For example let s create a two dimensional array a. Get array possition from mat file. Learn more about array struct.
First create the mat file object m. Save data to a subset of a variable y in the file myfile2 mat using the mat file object. How can i store a set of segmented output images saved as individual mat files into a cell array. For example you can save data to a subset of a variable in a mat file or read a subset of a variable into the matlab workspace.
I get the histograms and i can save it into mat file but i want to retrieve data to send it to nearest neighbor classifier. An array having more than two dimensions is called a multidimensional array in matlab. 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. How can i save the 18 values 6 for hue 6 for saturation 6 for.
Access specific parts of a variable in a mat file using the mat file object. Start octave octave at the command line for me. The structure s is not your original data array but a container that contains your data array.
