I have a series of matrices which are the result of various operations and I have a graph produced with the contourf function which must be exported and used in Qgis. the values that I have obtained and that are visible on the graph must be georeferenced and inserted into Qgis with a DEM. How do you export the matlab files in shapefile format that can be used in Qgis? is there any further way to use these matlab results on qgis?
Can anyone help me?

there is this error:
Error using shapewrite
Expected input number 1, S, to be one of these types:
struct, table, mappoint, geopoint, mapshape, geoshape
Instead its type was double.
