If you want to remove the colorbar, you can set the ColorbarVisible property to 'off':

h = heatmap(magic(5));
h.ColorbarVisible = 'off';

Alternatively, use the colorbar command:

heatmap(magic(5))
colorbar off

To turn off the grid lines, you can either set the GridVisible property on heatmap:

h = heatmap(magic(5));
h.GridVisible = 'off';

or use the grid command:

heatmap(magic(5))
grid off

Heatmap does not provide any control over the outer border around the outside of the heatmap, or the color or thickness of the line, so if you want to change those things you will have to switch to a lower-level function like image or surface.

Please help me change the labels on the colorbar to a specified number of ticks (e.g., caxis ([0.1 0.6]) to text label say {'low', 'medium', 'high} on heatmap?

Heatmap does not provide any control over the tick labels on the colorbar. If you want control over those labels, you will have to switch to a lower-level function like imagesc or surface.

h.GridVisible = 'off';

This will work to remove black borders.

Thank you for reminding me about that. I've updated my answer above to reflect that you can set the GridVisible property. You can also use the grid command:

grid off
