Problems with formatting yticks

I am trying to plot a set of data that has 20 points on the y axis from 0.03 to 0.38, I want to lessen the yticks on the plot for simplicity reasons but everytime i attempt to do this I get the error "Value must be a vector of increasing categorical values as ordered by the ruler Categories property."

Here is the code for the yticks i am trying to use:

yvec = [0, 0.1, 0.2, 0.3];
set(gca, 'YTick', unique(yvec))

Here is what the plot looks like as of now:

Did you use hold on to create the plot? Did you use yyaxis or plotyy?

It seems that you have created the plot with categorical variables. Therefore, yticks must also be of categorical type. Change the line to

set(gca, 'YTick', categorical(yvec))

I still get the same error. Is that not the same line that I have in the code already?
