Alias blanks in the cell array as a string.
I am using the ‘importdata’ function to read a text file. It reads the numeric data as a matrix and text data as a cell array; now the first element of cell array is all the headers, I use a ‘strsplit’ function to separate each individual variable name in header. The issue is that there are some blank columns in the text file, so the numeric matrix reads it as a ‘NaN’ but the resulting variables (which I used ‘strsplit’ for) eliminates blanks. Now the result is that size(textdata,2) +size(data,2) is not equal to size(variable,2).

Multiply a cell with a scalar number
Hello all, i have a problem in multiply my cell in Matlab. I have 1×5218 cell wich i want to multiply it with a scalar number. First, i used code like this,

input = t.x10000(1:5218);
new_input = input.*2;
it return,

Why is my ROS node running slower than expected when deployed?

How do I convert a .m with unsupported in-built MATLAB functions to C++
Hi everyone.
I’m currently trying to convert a MATLAB script to C++ but MATLAB Coder gives some errors saying some functions are unsupported in the code conversion.
Below are the unsupported functions

Looking for help in using structs in multiple functions
I am trying to use structs, but I have no idea what a 0x1 struct is, and I am trying to add to the struct outside of a function, but I don’t understand how they work. None of the websites have a good explanation of how to use the struct. Plus, I get an error when I use the dot method to add to it.I am trying to use structs, but I have no idea what a 0x1 struct is, and I am trying to add to the struct outside of a function, but I don’t understand how they work.

Modeling of cooling plate
Hello Team,
I am using simscape foundation library to model side cooling of a cylidrical cell which is represented by a thermal mass and the heat generation in each cell is represented by heat source.
There are two plates on each cell, the top plate and the bottom plate. the bottom plate is where the fluid is entering at certain flow rate, temperature and pressure. and after passing through all the bottom plates for a series of cells, the fluid enters the top plate and then exits the system.
I am currently modeling it in simscape using foundation library and not able to simulate the model, as I am not able to provide flow rate, temperatrure and pressure properly and cannot implement closed loop system.
Please help me in modeling thisHello Team,
