26.04.2019 · The function writematrix is available in R2019a. If you have a vector or matrix X, you can use the : symbol to flatten it into a column vector. Supposing you have several row/column vectors of equal length, you can put them all as columns in a matrix like this: Alternatively, you can structure your data as a table, then use the function writetable.

There are multiple approaches passing constants to MATLAB functions . Defining variables as global is a simple solution. Using global makes the variable "visible" to all functions and scripts. The downside of using global, is that it's not extendable, and prevents code reuse. From academic software engineering perspective, you shouldn't use global variables at all.
MATLAB does not recognize the specified string as the name of a function on the MATLAB path or as a variable. "Undefined function or variable" can be caused by:.
Declare the variables as global in any function that uses them: function v1=velocity1 (f) global K g v1= sqrt ( (2*g*h)/ (1+ (f* (L./D))+K)); end. Using nested functions: Instead of using global, you can use "nested functions" approach - an inner function can access the variables of an outer function. Define your main script as a function, and ...
