Why some paragraphs not displaying in report generator

Hello, I have been trying to leaarn how to wrie a acode that will generate a report from results in anote script. Am running into problems as some sections ar not displayed, right from section 3, the paragraphs are not being displayed and have been able to figure out why. From figure5, the proram is repeating the figurere1 and figure2 which should not be the case. So, what can be the problem may someone help.Below is the attached code.

It involves a comprehensive analysis of various factors, including wind direction, temporal and spatial wind speed variation, turbulence intensity, and wind power density. By examining the prevailing wind direction, which indicates the predominant path from which the wind blows, experts can determine the most suitable locations for wind farms and optimize turbine placements. Temporal and spatial wind speed variations, as well as turbulence intensity, are also assessed to understand the consistency, intensity, and stability of wind resources over time and across different geographical areas. Furthermore, wind power density is a key metric that quantifies the energy available in the wind and helps estimate the potential electricity generation capacity. In this assessment, wind direction, spatial and temporal wind speed variation, turbulence intensity, and wind power density will be evaluated to provide comprehensive insights for efficient wind energy utilization.']);

Hi okoth,

As per my understanding you are trying to include paragraphs in your report. I can see that you have not added sections statring from "sec2" to their respective chapters.

You need to add each section to its respective chapter for the paragraphs to appear in your report.

add(ch2,sec2)   % add every section in the same manner

Starting in R2020b, use the "append" method instead of the "add" method to add content to objects of these Report API classes:

• mlreportgen.report.Report
• mlreportgen.report.Chapter
• mlreportgen.report.Section

Refer to the below documentation for compatibility issues:

Add content to report: www.mathworks.com/help/rptgen/ug/mlreportgen.report.report.add.html

Append: www.mathworks.com/help/rptgen/ug/mlreportgen.report.report.append.html

Hope this resolves you query!
