add column to struct in matlab

To add a column to a struct in MATLAB, you can use the "setfield" function. First, you'll need to create a new field in the struct:

main.m
myStruct.newField = [];
24 chars
2 lines

In this example, "myStruct" is the name of your struct, and "newField" is the name of the field you want to add.

Next, you can use a for loop to add values to this new field:

main.m
for i = 1:length(myStruct)
    myStruct(i).newField = myValues(i);
end
71 chars
4 lines

In this example, "myValues" is a vector of values that you want to add to the new field. The for loop iterates through each element of the struct, and sets the value of the new field to the corresponding element of "myValues".

Alternatively, you can set the value of the new field using array indexing:

main.m
myStruct(1:length(myValues)).newField = myValues;
50 chars
2 lines

This code sets the value of "newField" for the first "length(myValues)" elements of "myStruct" to the corresponding elements of "myValues".
