I have imported a table from an external file via textscan. For example:
A = rawCellColumns2(:, 1); B = cell2mat(rawNumericColumns2(:, 1)); C = cell2mat(rawNumericColumns2(:, 2)); D = cell2mat(rawNumericColumns2(:, 3)); E = cell2mat(rawNumericColumns2(:, 4));
A is "datetime" in this form:
2019-07-10 22:00:00
Error using horzcat Dimensions of matrices being concatenated are not consistent.
People have addressed this problem here at Matlab Answers, but as a bit of a newbie, I would be very grateful if someone could please provide a newbie-level explanation. I am using 2016a. Thank you very much for any advice.

v = (0:4).';
dt = datetime('today') + days(v);
x = v.^2;
Now let's build the table.
T = table(dt, x)
See the documentation for table to learn how to work with data stored in a table.
doc table
One example: you can extract the row of the table corresponding to x = 4.
T(T.x == 4, :)
