Hello, I am trying to plot boxplot.
x = [1 2 3 4 5];
y = [1.13465 1.17166 1.19973 1.78338 1.83673
3.96e-12 3.6e-11 0.109991 1.0131 1.57166
0.574522 0.619429 0.685391 1.21099 1.73831

5.5e-11 0.0395349 0.180155 0.639514 1.04088];
boxplot(x,y)
this is the code that I used,
but when I tried to plot, it said
'The function 'boxplot' is not defined for inputs of type 'double'.
Error occurred: untitled (line 22) boxplot(x,y)'
Can anyone help me to solve the problem?
Thank you!

You do not have the Statistics Toolbox installed or licensed.

Hi @changmin lim,
To address the issue that you are facing with plotting boxplots in MATLAB, it is important to ensure your data is organized correctly. Given your requirement to plot only 5 boxplots without transposing the matrix, you need to make sure that each row in your data matrix represents a different group.
Below implementation is for your reference.
x=[1,2,3,4,5];
y = [
1.13465 1.17166 1.19973 1.78338 1.83673;
3.96e-12 3.6e-11 0.109991 1.0131 1.57166;
0.574522 0.619429 0.685391 1.21099 1.73831;
1.27e-11 0.142583 0.308049 0.890379 1.38142;
3.5e-12 0.0606085 0.137094 0.565742 0.915032;
1.77e-11 0.0206984 0.096124 0.213596 0.548369;
0.343735 0.358206 0.386193 1.04343 1.80219;
0.342868 0.333045 0.341806 0.760036 1.41684;
0.423389 0.412866 0.415499 0.569211 0.564488;
4e-12 3.67e-11 0.109991 1.0131 1.57166;
0.692851 0.696025 0.704127 1.30321 1.88094;
5.5e-11 0.0395349 0.180155 0.639514 1.04088
];
boxplot(y,x);
